TITLE: Microsoft SQL Server 2022 Setup
The following error has occurred:
The MOF compiler could not connect with the WMI server. This is either because of a semantic error such as an incompatibility with the existing WMI repository or an actual error such as the failure of the WMI server to start.

Short description: AWS RDS connecting server to PgAdmin 4, PostgreSQL 11
Done: I have done similar to this guy or to this aws guide but at the end when I click save it does not accept it for me. instead gives the following
ERROR:
Error saving properties
Unable to connect to server:
timeout expired
What I have tried to solve the problem:
The instance is active it is 2 hours after creation
I have also allowed to access database with outside of AWS database client "YES"
this stack overflow answer does not deliver results https://stackoverflow.com/a/37903485/10270590 actually after refreshing my security group like the guide says my whole database disappeared
I have home wi-fi so there are no corporate firewalls or any of those issues https://serverfault.com/q/705312/535406
while reading the pervious server fault post I looked up my
RDS/Databases: what was empty
RDS/Security groups: empty and I have this message:
Your account does not support the EC2-Classic Platform in this region.
DB Security Groups are only needed when the EC2-Classic Platform is supported.
Instead, use VPC Security Groups to control access to your DB Instances.
I have tried which this question https://serverfault.com/questions/656079/unable-to-connect-to-public-postgresql-rds-instance that had 2 good answers but they gave the same error even after doing bot of the changes
https://serverfault.com/a/656119/535406
https://serverfault.com/a/880710/535406
same as the above one - AWS RDS Database show timeout error

Edit inbound rules
Type have to be turned to: all traffic and my IP. than it works

I deployed my vapor project to Ubuntu. And made the configuration of supervisor and Nginx.
When I invoke my server. first call is success but When I try second call I get 502 bad gateway error from browser. When I check error log, the error is
"Fatal error: Error raised at top level: bind(descriptor:ptr:bytes:) failed: Address already in use (errno: 98) : file /home/buildnode/jenkins/wo$"
If I kill the port(8080) process. And after, I try to connect again first try is success then get fail again.
What should I do to get rid of this error?

This might be caused by another process using that port.
I had the same issue and was able to solve it by listing all the processes on port :8080:
$ sudo lsof -i :8080
and then killing all of them one by one by typing:
$ kill {PID of the process}
After that, my app built again properly.
taken from here

I had the same issue. This worked for me:
$ kill -9 {PID of the process}
Hope this helps!

Has anyone noticed a serious problem with CPAN downloads?
All of the download links seem to be iunable to resolve www.cpan.org,
but the directory structure inside CPAN doesn't allow any simple swapping to search.cpan.org.
Has anyone found a fix?
Tried to use metacpan.org:
wget http://metacpan.org/CPAN/authors/id/M/MP/MPIOTR/Text-Iconv-1.7.tar.gz
Result:
--2013-06-15 16:00:17-- https://metacpan.org/CPAN/authors/id/M/MP/MPIOTR/Text-Iconv-1.7.tar.gz
Connecting to metacpan.org|46.43.35.68|:443... connected.
ERROR: certificate common name “cpan.metacpan.org” doesn’t match requested host name “metacpan.org”.
To connect to metacpan.org insecurely, use ‘--no-check-certificate’.
Tried without certificate: page not found.
What is happening in CPAN?

http://search.cpan.org seems temporarily broken. You can use https://metacpan.org instead. For the certificates, you can bypass it by using :
export PERL_LWP_SSL_VERIFY_HOSTNAME=0
cpan https://metacpan.org/path/to/Module.pm

It means you have already an ejabberd running, that is an Erlang node with the same name (Duplication name).
Stop / Kill your existing beam processes.
