In some cases, the mongod service has been down and you get this error through the shell or GUI.
General Error:
Error: No suitable servers found (serverSelectionTryOnce set): [connection refused calling ismaster on 'localhost:27217']
We also found cases where JetMongo fails to start due to this error which can be caused by having localhost set to ipv6 instead of ipv4 in the /etc/hosts file.
# Do not remove the following line, or various programs
# that require network functionality will fail.
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
Please try setting the localhost to the default ipv4 IP (127.0.0.1)
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
and then restarting the jetbackup5d service:systemctl restart jetbackup5d
