Heroku application stopped serving db2 connection-CodePudding

I have my app hosted on heroku for nearly 1 year, and in the past 24 hours, it stopped working. I get this in my logs:

 2021-11-08T18:15:06.475815 00:00 app[web.1]: [Error: [IBM][CLI Driver] SQL30081N  A communication error has been detected. Communication protocol being used: "TCP/IP".

It seems to not like whatever is going on with db2. I can access my database no problem through my local machine, and see everything with in my db tables. I also have this directly from my heroku dashboard.

i am not able to figure out what the issue is. does anyone have any ideas?

CodePudding user response：

Thanks to everyone for their answers. I did some more digging around, and turns out what solved it was reinstalling the db2 driver locally, and pushing it to heroku. Something must have changed that required an update to the db2 driver to connect with the heroku sevrer.
