Hi,
I had a look into this article:
https://wiki.archlinux.org/title/SSHFS
and this question in this forum:
https://bbs.archlinux.org/viewtopic.php?id=27613
I have had a virtual machine on a Proxmox server running for years mounting a SSHFS filesystem where everynight a backup is performed. I decided to do this instead of using sftp or other means because they were not working and besides this let me the possibility of having access to the backup itself.
I have moved the virtual machine from a Proxmox running 5.4-13 to another server running 5.4-15. Exact settings and now from time to time the connection drops randomly and sshfs gets unmounted and I get the following messages on the remote SSH server.
Oct 18 00:19:50 nagios sshd[27752]: Corrupted MAC on input.
Oct 18 00:19:50 nagios sshd[27752]: ssh_dispatch_run_fatal: Connection from 111.222.333.444 port 41474: message authentication code incorrect
How can I troubleshoot this from the proxmox machine? I don´t see anything logged in my Proxmox server. The hosting company wants proof that the issue is coming from the proxmox server, which what I suspect since only the host has changed.
Thanks,
Miguel

Have you a rsa-key for you authentication? Whit the newest openssh-server rsa-keys aren't accepted by the server.

What I mean is the connection is established and after a while (even after hours) I get that message
