Unable to activate a workflow due to a DNS server error

Describe the problem/error/question

I am unable to activate the workflow due to a supposed DNS server error. Things worked alright for some time but after a couple of days I started receiving this execution description and now I am unable to even start it.

All the errors came from different triggers (google and notion).

What is the error message (if any)?

Workflow could not be activated:
There was a problem activating the workflow: “The DNS server returned an error, perhaps the server is offline”

hi @Nejc :wave:

This sounds like your instance isn’t connected to the internet when this happens (or has something improperly configured), and it’s unable to resolve DNS servers - can you share your docker compose file (and redact any sensitive information like passwords or tokens)?

Hey there, thank you for the reply but I managed to resolve the issue.

What helped is removing the container and restarting it. Could have tried that sooner before opening up a new ticket…

Thank you, any way!
