Check update from web GUI of slave not working after upgrade to 21.1.7

[fabiodanzetta]

Hello everybody,

after updating my two nodes in HA to the latest version I noticed that if I look for updates on the slave from the web gui, the search remains in loop without showing any message while everything is ok on the master.
If I run the search for updates from the shell everything works telling me that there are no updates available.

Thank you all.
