Can't run docker image with MongoDB - mongodb

Question

I'm using Docker+MongoDB to run a Personal Project (tutorial i'm learning from). It worked flawlessly yesterday, but i had to restart my computer today.
Now i can't get it up & running again. I'm always having the error (according to the logs):
EDIT: The same error happens when i try to run it locally also (just compiling and checking on Postman if i can run any query). Its the same error message.
EDIT2: After running:
docker run -d --rm --name mongo -p 27017:27017 -v mongodbdata:/data/db
mongo
I got it working locally. However, i still can't get it running using the docker image.
Microsoft.AspNetCore.Server.Kestrel[13]
Connection id "0HML25FGS5AM1", Request id "0HML25FGS5AM1:00000002": An unhandled exception was thrown by the
application.
System.TimeoutException: A timeout occurred after 30000ms selecting a server using CompositeServerSelector{ Selectors =

}, OperationsCountServerSelector }. Client view of cluster state is {

State: "Disconnected", ServerVersion: , TopologyVersion: , Type:
"Unknown", HeartbeatException:
"MongoDB.Driver.MongoConnectionException: An exception occurred while
opening a connection to the server.
Here's what i can tell:
MongoDB is running. On Visual Studio using Mongo Extension, i can see that my mongo database is connected.
When i open docker for windows, i can see my image there as well. And if i hover the mouse under docker icon on notification tray, it says that docker is running.
My connection string seems to be okay. I couldn't figure out any problem with that, since its the same that was working yesterday.
I'm a bit of lost here, i don't know what else to do. It would be really really painful to restart the entire tutorial because of this docker error.
Here is my connection string:
$"mongodb://{User}:{Password}#{Host}:{Port}";
The command i'm using under the cli to run my docker image is:
docker run -it --rm -p 8080:80 -e MongoDbSettings:Host=mongo -e
MongoDbSettings:Password=Pass#word1 --network=net5tutorial
pablobhz/catalog:v1
Any input is appreciated. Thanks a lot!

Well, i fixed the problem myself. Here's what i did:
Followed the suggestion from user barrypicker . It didn't worked out but gave me an clean start.
Created a new docker file and changed it accordingly (only minor changes).
Created the mongodb container again. Here's what i did:
docker run -d --rm --name mongo -p 27017:27017 -v mongodbdata:/data/db mongo
Fine. Now i have the mongo container running again.
Built my docker image again:
docker build -t catalog:v1 .
Tried to create the docker network again. Since it already existed, just received a message saying it exists. So far so good.
Started the mongo container again. I understood that i had to start in order to my docker image works. It can't connect to an database if there's none running.
docker run -d --rm --name mongo -p 27017:27017 -v mongodbdata:/data/db
/e MONGO_INITDB_ROOT_USERNAME=mongoadmin -e
MONGO_INITDB_ROOT_PASSWORD=Pass#word1 --network=net5tutorial mongo
Started the main container again:
docker run --it --rm -p 8080:80 -e MongoDbSettings:Host=mongo -e
MongoDbSettings:Password=Pass#word1 --network=net5tutorial catalog:v1
Hope this helps someone in the future! Sorry fot eh explanation not being great, its my first time with Docker and i've been into a lot of trial and error to get it working.
Thanks everyone!
