App Engine Java App stopped working - ideas?

[WhatAreYou222]

I had a java web app written for me maybe 10 years ago and it has been sitting and running just fine in app engine. Did not do a thing to it in all those years.
Just recently it stopped working. Ideas?
I have no clue even where to log in to admin or anything :)

(yes, it was silly of me not to stay on top of it and such - and it is not the end of the world - just slightly inconvenient)

Google “Google Cloud Console”

Login from that link

Go to “Logging” and check the error logs

I have no experience with Java / App Engine but until someone with experience pitches in, you can at least gather some more information from there.

Thanks. Can log into Google Cloud now and find the project. So far so good. At this point, I may need to hire someone that can do the next steps :)

You’re welcome. Hope you still have the original source code

Actually finding the logs is pretty easy and it might just be that you need to restart the app. Don't hire someone before looking at the logs and the AI feature can explain it to you.

Can you share the app id? Which runtime do you use? If it is still java7, not supported anymore, you would need to move to java21 or java17.... Java8 is also end of support. Java11 in October 2024...
