• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

High ping loss and connection problems

M

MarcSerra

New Pleskian
As you can read on centos forums we got connection problems on 1 of our servers. Making an horrible experience work with our websites, plesk panel, ftp, and all of other services.

Ping results from an office connection to the server (windows machine)...
Code: 
sent = 946, received = 530, lost = 416
    (43% lost),
Times:
    Min. = 48ms, Max. = 125ms, Med. = 54ms

From another office connection to the same server (linux machine)...
Code: 
    10 packets transmitted, 4 received, 60% packet loss, time 9012ms
    rtt min/avg/max/mdev = 0.240/0.256/0.296/0.030 m



If we ping from our server to the internet (google) got variable results...
