Data Protection Central 502 error - Unable to connect to the server. Please verify the server is available.
Hi,
I am trying to set up DPC for the first time.
I try to log into the webgui but I get this Error: Unable to connect to the server. Please verify the server is available. The URL reads https://FQDN/#/Auth/Login?error=502
I am able to ssh into it, and I am able to resolve the FQDN with DNS. I get the same error using either the FQDN or IP in the address bar. I am using Chrome to access it.
I configured NTP to be our internal NTP servers since Avamar, DD, and DPA all use our internal NTP servers for synchronization.
I am not sure what I am missing. Any help is greatly appreciated!

I was able to resolve. The issue seemed to be hostname related, so I took a peak and noticed an IPv6 entry; checked out the IPv6 config and saw it was disabled. Enabled IPv6, rebooted and problem was resolved.

Hi,
Could you give steps to fix this? Where did you enable IPv6? Does it matter that we don’t use IPv6 internally, or is it simply for the loopback?
Thank you,
Mike

Most of the time this error happens when there is incorrect DPC network settings. Here are the troubleshooting tips for finding and resolving those issues
1. DNS entries are missing
DPC is only configured with a static ip-address (not with DHCP). Make sure the ip-address and hostname can be resolved with the DNS server. Run 'nslookup' command on DPC to verify if DNS entries are available or not. For example, if DPC hostname is dpc.dell.com with ip as 10.10.10.10, then run below commands to check with DNS server (assume it's a 10.10.10.5) entries are available or not. If not available, add the DNS entries in DNS server.
nslookup dpc.dell.com 10.10.10.5
As per our example, it resolves to ip-address as 10.10.10.10
nslookup 10.10.10.10 10.10.10.5
As per our example, it resolves to hostname as dpc.dell.com
2. DNS server(s) details are missing
check if DNS server(s) details are available or not, by running below commands
cat /etc/resolv.conf
If search and nameserver entries are missing, then run below command to add those entries
yast2
Navigate to Systems -> Network Settings -> Hostname/DNS
add DNS Name servers and Domain search value
3. hostname -f
If the the 'hostname -f' command doesn't resolve to fully qualified hostname, then its a network settings issue.
Run yast2 command (as described above) to make sure you have right network settings like ip-address, hostname, default gateway and DNS entries.
Once any of the settings are updated, reboot DPC to reflect those network settings changes to DPC services.
I hope this is helpful

Hi!
If you have this problem check as root user /usr/local/dpc/bin/dpc status
May be you have msm-elg: failed
So, its a problem with your UI admin password
Delete this virtual machine and cret fresh instal with password looks like this one R5***M#Hv
Replease start with 3 small letters. Its a very good mask for this stupid password i spend a lot of time before installed it.
