Android Studio GitHub SSH login repeatedly gets rejected

Issue

I have public/private key login to GitHub configured in Android Studio. After changing my internet provider this stopped working correctly. Meaning that my SSH login gets rejected after every time I use Android Studio. When trying to push changes to my repository the next day it says the following:

git -c credential.helper= -c core.quotepath=false -c log.showSignature=false push --progress --porcelain origin refs/heads/main:main

fatal: could not read Password for 'https://[email protected]': No such device or address

Then I have to generate a new SSH key and add it to GitHub for the authentication to work again. This is getting very annoying and I believe there is something I can do about it. It is just that I have no idea what could be causing this. I hope somebody can point me into the right direction.

EDIT: It seems that Android Studio is using a wrong URL to authenticate. It should use the personal access token from GitHub and the repository name should be at the end of the URL like this:

https://[email protected]/username/reponame

Solution

The solution was to enter the personal access token when I tried to push with Android Studio. It displayed a "Log in" windows for GitHub and I could choose the option to enter a Token. After having done this the problem disappeared. Maybe this was fixed with an update, since this dialog didn't show up in the past.
