I get:

The flight claim is complete only when all waypoints are printed in
green.
Suggestions will be made by the server only if the flight trace
approaches a declared waypoint to no more than 2.5km.
There is no fix in the IGC-file with your finish time."

I have exactly the same problem (Cambridge Model 10). I have reviewed
the raw file and confirmed that there are indeed B record fixes in the
file corresponding to the fixes that OLC is showing as no good.

I have verified multiple
times that there is in fact a fix in the IGC file with exactly the
finish time...

Ditto.

I have tried - CAI file direct to See-You 2.85. I have tried CAI file
+ conv-cam to create new IGC file then the OLC utility cai2igc to
append the G records to the new IGC file & several variations thereon.
All equally hopeless and resulting in the same errors as you have. I
have wasted hours on this and I'm giving up unless someone has the
process down.
