That is old.  gpsd is now at 3.20.  Please update and retry; there are
not that many people here and while most try to be helpful, no one is
interested in dealing with code older than the latest formal release.
(Or build from git master.)

Once you update, use tppdump to see what happens, and also
ktrace/strace/struss or whatever your OS has for syscall tracing.  And
run gpsd with debugging.

You may want to use tcpdump with -s1500 writing to a file, and then -A
on that, once it connects if it doesn't work, so you can see the
mountpoint table.  You can also tcpdump what the ucenter stuff does.

so that didn't work :-)

I hope your username and password does not contain either an @ or :.  If
not, change them and retry.   Or update to master and fix the code that
finds the hostname part of the ntrip URL to use the right-most @.

Presumably without being in RTK.

It is good you are using a single-site mountpoint.  gpsd does not have
support to send a position back to use the iMax VRs style.
