What branch are you deploying these changes to?

'master'

Disconnect and reconnect your repo from your settings. Push a commit to github again.

I try to reconnect my repo and branch but cant work, i know something i might be missing, i just haven't figured it out yet

I just reset your GitHub. Please go ahead and login with GitHub and try again.

Good evening, tried to log back in, redeployed, deleted, but no progress. Pull my own project to machine and from there it runs perfectly fine in flask with modifications. Maybe I am careless ...

Should I try to completely delete my flask application and call it again?

It must be something small because I see when I modify e.g. html page, it is updated on github and redeploys on railway but some completely old html loads :) a master branch is not used anymore.

It's fixed! After repeated new deploly and several tries it now goes.... but for how long ? :)

It's very likely due to browser cache, we do not cache your website on our server.

I know you don't store it, but I looked at it from several browsers, I tried clearing the cache, I saw the change on github but I didn't understand it either... It works, thank you very much for your time and patience! Good luck!
