Pc always indexing

i have a problem

a computer always indexing and later show this error “Full Backup of MHESC-005107 failed - CONNECT error” its window s10

Not sure if I can help, but here is a couple things you can check.
Look at the Windows 10 PC Event logs. May see something there.
Check the Urbackup logs (Server and Client).
Check your version of UrBackup.
I had same problem a long time ago. No issues with newer versions.
Hope that helps, cuz that’s about all I got.
