Portainer Update

Ask a Question!

Dear all, my Portainer is on version 2.27.6 LTS. When I update to the next version, 2.27.7, my websites no longer open Typebot, n8n, and Evolution API, with the following error: 504 Gateway Timeout. When checking with the command docker logs traefik --tail 50, I received the following error message:

ERR Error renewing certificate from LE: {n8ndigicom.digicomia.com.br []} error="error: one or more domains had a problem:\n[n8ndigicom.digicomia.com.br] invalid authorization: acme: error: 400 :: urn:ietf:params:acme:error:dns :: DNS problem: NXDOMAIN looking up A for n8ndigicom.digicomia.com.br - check that a DNS record exists for this domain; DNS problem: NXDOMAIN looking up AAAA for n8ndigicom.digicomia.com.br - check that a DNS record exists for this domain\n" acmeCA=https://acme-v02.api.letsencrypt.org/directory providerName=leresolver.acme

The problem is that this domain n8ndigicom.digicomia.com.br no longer exists, and I currently use a different domain. Could this be the reason the sites aren't opening after the update? If so, how can I resolve this?

Even though it's working with the current version, this error continues to appear.
