fatal: Could not read from remote repository.


Please make sure you have the correct access rights

and the repository exists.

Done. Took 1 min 10 sec

There is the same behavior in Bamboo: https://jira.atlassian.com/browse/BAM-14555

Both came from the fact, that Stash doesn't have zero time backups https://jira.atlassian.com/browse/BSERV-4255, however plugin should take into account that backup is running and prevent SCM Poll during that time.
