I has that problem from the first Nova version, reported it periodically with “report a problem” (with no fix), but if from the beginning someone was answering me, now its a dead silence. If I’m not describing problem well, probably someone here will help with it.
Thing is: I has servers with the ssh keys, a lot. And then I’m opening terminal in Nova, sometimes it’s forgot what key is exists and you are getting “Credentials were not accepted by the server”. So you need to click and select ssh key button and choose it again and again.
First time support told me “it’s because of the Coda 2 migration, something goes wrong”. 2 months ago I cleared everything in Panic Sync and made new DB. Problem is still here.
