I discovered a really bad bug. I thought Proxmox was to blame, but it turned out to be help.mikrotik.com.
We have a problem. When mounting a remote NFS drive in Proxmox, the web interface experiences terrible lag (~10-30 seconds) when clicking the "SUMMARY" menu.
After some investigation, it turned out that opening port 111 solves all the problems. However, help.mikrotik.com states:
NFS uses port TCP/2049. If the port is not available, you will see the state stuck at nfs-state="mounting" in disk print detail.
Please fix the WiKi or provide this information in another way.
