Can't restore a backup

I’m trying to restore a backup with a very large repository (100GB), using this command:
gitlab-backup restore BACKUP=1594512692_2020_07_12_13.0.6

and I get an error:

E0716 17:11:22.016470986 89168] Received a GOAWAY with error code ENHANCE_YOUR_CALM and debug data equal to "too_many_pings"

Everything except this repository recovered fine.
How do I restore a backup?
