I had not configured to reverse dns, I did it this morning, but still the same problem.

I have not configured glue, can it come from the?

Thank you in advance for your assistance

This usually means your IP address is blacklisted. The connection is immediately blocked. so something triggered their refusal.

Scanning blacklists for your IP address, though, doesn’t raise any flags:

Your reverse DNS also looks good.

Sorry this isn’t much help. The destination is just blocking you for a reason I can’t figure out.
