After upgrade to 2.5.32 fastcgi interface still shows the older version

Hi,
I noticed that after upgrade to urbackup-server 2.5.32 (Linux CentOS 8) the fastcgi web interface (55413 port) still shows the older version. HTTP interface (55414) shows the correct version.
I am using uroni rpm repo and update was done with yum. The web is accessable trough revere proxy to fastcgi interface as the example in the docs.

Regards,
Cvetan
