Why don’t you upgrade to 1.35.3?

Thanks will use a new Docker image with 1.35.3 although seems its not really stable for very long, so do you upgrade each time auto or manual whenever a new version comes out

If people talk about an upgrade that is mandatory for a hard fork for months, yes, then you should upgrade.

For sure I knew about the hard fork, but 1.34.1 was still being supported will have to keep up more with the announcements, which is the best channel to view important dates like deprecation announcements , Telegram ?

There’s an IOG telegram group and the discord. There are also announcements on their twitter feed too.

It’s a blockchain—not a Docker instance!

Yes, upgrading to Cardano Node 1.35.3 may help solve the problem:

Please do not ask me who wrote the procedure,
