Password authentication is not working in ssh on windows - powershell

I tried to install windows OpenSSH Server feature also tried to manually install OpenSSH in C:/Program Files/OpenSSH but for both when i try to connect it ask for password I enter correct but it says Permission denied always. It was working fine but after some time started to face this issue. I tried to manually run the sshd server with -d option and it gives the following logs

What might be the cause of this problem?

Default shell location was incorrect and I found this in server debug logs mentioned in question i-e
User domain\\aawais not allowed because shell c:\\program files\\powershell\\7\\pwsh.exe does not exist
execute following command to set default shell
New-ItemProperty -Path "HKLM:\SOFTWARE\OpenSSH" -Name DefaultShell -Value "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -PropertyType String -Force

Why can I not ssh into github?

I cannot ssh into github no matter what I do. All attempts appear to decline my key pair. I am able to ssh into my home server just fine, so I assume that this issue is with github specifically.
This is what I've tried so far. All of these methods fail with the same issue:
I have tried logging in using the key produced by my script below as a deploy key in github
I have tried using a similar set of steps as that script and instead added the key to the list of my account SSH Keys
I have tried using different algorithms (ecdsa, ed25519, rsa, etc...)
I have tried logging in via my own machine (linux mint) and my home server (ubuntu)
I have tried adding the key to the ssh-agent using ssh-add
I checked the SHA256 fingerprint in github for the key against the output of ssh -v below and it matches
Local Machine
This is my ~/.ssh/config:
Host github.com
User git
HostName github.com
IdentityFile ~/.ssh/github_ecdsa
Here, I have output from running ssh -vT git#github.com

git#github.com's password:
I can see that, near the bottom, it offered the key I configured, but because it moved right on to password authentication, I am assuming it declined my key.
My Home Server
I have the following script:
#!/bin/bash
# generate a key pair
repo=$1
ssh-keygen -t ed25519 -N "" -f .deploy-keys/$repo >/dev/null
# give time to add the public key to github
cat .deploy-keys/$repo.pub
read
# clone using an ssh command that has the identity file set to the private key
git -c core.sshCommand="ssh -vi .deploy-keys/$repo" clone git#github.com:username/$repo
At the read step, I'll do the following:
copy the contents of the public key.
go to https://github.com/username/repo/settings/keys/new
paste the contents into the big box, give it a name, and save
press enter to continue on the script
The verbose output for this one is here (I truncated most of it this time):
...

git#github.com's password:
Again, I can see that it found my key. What gives? I've never had the problem in the past. I've used Windows, MacOS, and Linux machines for this before, but never has this issue been so persistent.
UPDATE
I deleted my known_hosts file, and then added the github fingerprints from the link provided by Chris.C to be safe. I noticed that when I ssh to my home server, I see this fingerprint:
ED25519 key fingerprint is SHA256:5ip0RVW9UxjapS8EiRiO6d9k+SJArVU0NVXDSHjTAVU.
And then when I try to ssh to git#github.com, it shows me an error with the same fingerprint:
The fingerprint for the ED25519 key sent by the remote host is
SHA256:5ip0RVW9UxjapS8EiRiO6d9k+SJArVU0NVXDSHjTAVU.
It appears that my router loopback masquerading is somehow messed up. I confirmed that this fingerprint is the actual one for my home server, and it looks like my router is sending all ssh requests to that server instead of outside the network. Funny thing is, I have similar rules defined for 80 and 443, but those two ports do not experience the same issues. Odd behavior, but my problem is out of scope now for the question I originally asked. Thanks for the help!
Your log shows
debug1: Server host key: ssh-ed25519 SHA256:5ip0RVW9UxjapS8EiRiO6d9k+SJArVU0NVXDSHjTAVU
However github should have below fingerprints.
SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU (Ed25519)
So you're connecting to the wrong github server...

I still can't push code to github despite getting the You've successfully authenticated message in this debug output, the SSH identity being generated by SourceTree itself, and ensuring my SSH Agent is running by doing eval "$(ssh-agent)".
I can also see the expected key in my github profile.
What is wrong here?
my SSH Agent is running by doing eval "$(ssh-agent)".
This is likely the problem. ssh knows to talk to ssh-agent via the SSH_AUTH_SOCK environment variables. Environment variables are only visible to a process and its children.
eval "$(ssh-agent)" sets SSH_AUTH_SOCK for this shell and its children only; that is anything you ran from that shell. If you then run git in this shell it should work. But if you have some stand alone program not launched from this shell, like Atlassian Sourcetree, when it runs ssh it will not know to talk to that ssh-agent.
You could launch Sourcetree from that shell, but that's not a very good solution.
To fix this, and a host of other ssh related problems, start your ssh-agent at login. This should be done for you by your operating system, or if not follow the instructions for your operating system. Otherwise, follow the advice in the various answers here.

Github - Fatal Authentication Failed - Yet I can still connect?

My github isn't connecting. I've tried two different computers and I'm getting the same error so clearly I'm doing something wrong. When I run git push I get prompted for my username / password as expected. Type them in, and yes I'm typing them correctly. Then it says:
fatal: Authentication failed
However when I type ssh -T git#github.com it prompts me for my passphrase and after entering that, it welcomes me to github. I've tried to add the SSH key again and all it says is this SSH key is already on the account. Someone let me know what I'm missing?
When I try to login it shows:
Password for http://(UserName)#www.github.com:
Is that correct?
More Information: Here's the output of ssh-vT git#github.com:

Try instead of linking to github through http go through ssh. do git remote set-url origin <ssh url> and then try doing git push
The ssh url should be something like git#github.com...
You can try ...
1 Edit your remote repository
git remote set-url origin your-remote-repository-ssh-url
2 Push your code.
git push origin ...
Where will you find your ssh-url?
1 In your repositories page
2 Click ssh link and copy your ssh-url
If you have this problem, you have basically two solutions as your options:
If you insist on using HTTPS to connect to Github, you'll need to get a Personal Access Token from your account on Github instead of your password.
You'll need to switch to SSH and use that to login.
For both options, check out this Stack Overflow question and its excellent first answer for how to go about implementing them.

Permission denied public key with Cap, but I can ssh into github

So I've been wrestling with Capistrano a lot, and I think I've always got it to deploy.
The issue I'm having now is that doing a cap deploy gives me:

Any ideas?
Add this to your config/deploy.rb
set :ssh_options, { :forward_agent => true }
If you're using your own private keys for git, you want to tell Capistrano to use agent forwarding with this command. Agent forwarding can make key management much simpler as it uses your local keys instead of keys installed on the server.
Source: Agent Forwarding Topic.
and make sure the user is not sudo in config/deploy.rb:
set :use_sudo, false
as in the logs you have attached, you are logged in as faxattach ( which is perhaps not sudo).
The ssh connection that fails is made to the server, not to github.
You should check if you can get on the server with this key.
If not you should add the public key to the servers .ssh/authorized_keys.
Also check if the user for the server is correct and exists.

github : push permission denied (

I know the question has been asked several times.
From my local machine I try to upload files to my repository:
:~/Git-JeanPat/pyFISH$ git push -u origin master
Agent admitted failure to sign using the key.
Permission denied (publickey).
fatal: The remote end hung up unexpectedly
my repository is
https://github.com/jeanpat/pyFISH
I check my password from the admin interface of github.
I made a new ssh key from command line, and I copy it on github.
When I check my connection as indicated. it fails:
~/Git-JeanPat/pyFISH$ ssh -vT git#github.com
