Hello,

I hope I'm not on a wrong track here but something with propagated message sending in nomadnet really seems to be wrong.  With any propagation node I try, including those that work well with sideband in the same moment, sending fails.  Here is an example log (slightly redacted; always looks very similar):

This did not happen to me in the past. Am I the only one seeing this?

Reproduced with 1.4.0 and 1.4.1 during several days.

Is this across different propagation nodes, or just one? Have you tried changing it?

Change the prop node you are using. That node has disabled propagation. That's why the link closes immediately.

I see - you are correct of course.

What I had been doing in nomadnet was selecting "Use as default propagation node" in the node info area of nodes I trusted.  But this is not a good idea in general it seems: most servers that announce a dedicated propagation node on their nomadnet page provide it under a different separate address.  Random propagation node addresses might just refuse my requests.

So - thank you for your help.  Hopefully I will only find real errors in the future (or better: none at all).
