Resolved Backup Manager stuck with 504 Gataway Time-out error.

Hello,
before 5 days I backed up all 3 webaspaces that I have on this server.

Today I tried again, and I backed UP 2 webspaces, but third I can't.
When I chose that webspace, browser trying to open it, and stuck.

Other webspaces still can open, but this one not...

What can be?
