I recently had problems with infinateWP, flagged it for a bit then try to do backups with Duplicator, crashed ( timed out) then tried Backup Buddy etc..
All on Uber..

Every problem I have it turned out they blocked this and that.
Got each working but took a bit of time.
you would think a host would pick up the error and fix it pretty quick but it took days sometimes til eventually they put it to the techs that knew what they were doing to fix it.
All because their security was so tight that when they gave out hostings there were heaps of errors..

So suggest you try your host too..
