In the past I converted .ubx log files from an Emlid M2 receiver to RINEX and then used the Canadian PPP service with those files.
When trying this again today in many cases I receive a rather terse error message from CSRS-PPP:
The RINEX file contains formatting errors in the observations at epoch 2021 2 5 12 5 4.01. Please correct and resubmit.
This is the corresponding epoch data:

This looks as innocent as any other epoch to me. If I remove this epoch the processing continues and then I receive a similar error message at an later epoch. Is there anything wrong with the formatting of this epoch generated by rtkconv and if so how can I prevent this from happening?
For reference these are the rtkconv settings (following the Emlid documentation):
