SSH Remote error: 255 on DDEV when I pull db

[JayBox325]

I have installed craft-copy and pushed up all code and the db, then to perform my first pull test to make sure everything is running I got the following error when I tried to pull the db. I have seen multiple other SSH Remote error: 255 issues raised, but none with an unresolved hostname error (Could not resolve hostname deploy.eu2.frbit.com: Temporary failure in name resolution).

App: app-name-here.frb.io (production)
▏
▏Export DB from fortrabbit, download and import locally.

 Are you sure? (yes/no) [yes]:

Sorry for the late reply here. One possible solution is that you have upgraded Craft CMS some time ago and the config needs to be manually patched: https://craftcms.stackexchange.com/a/41423/4504

Another lead might be that this is related to your local setup, specifically are you using DDEV and if so how is that configured?

Temporary DNS issues are common on the internet and depends on a lot of things, local setup, network connection, etc. I'm closing this for now. Feel free to come back with more information if this issue still exists.
