Feed update problem (Ubuntu 20.04.4 LTS + GSA 21.4.3)

Hello, professionals!

My case is the following
Environment:
-Ubuntu 20.04.4 LTS (GNU / Linux 5.4.0-104-generic x86_64)
-Greenbone Security Assistant Version 21.4.3

After restarting the host with greenbone in the web management interface on the Feed Status tab, the status has not changed for more than a month and is in the state of Update in progress …

Manually running any of the upgrade commands leads to the following message:
"Greenbone community feed server - http :// feed. community. greenbone. net/

The manual automatic update task (cron) was removed, but this did not have the expected effect.

Since I am a beginner in Linux, I would be grateful for any help in this matter.
