GPS error after Mewtwo raid

I got a RSVP to join a Mega Mewtwo raid in New Zeland. I am currently in the Czech Republic so I used a remote raid pass to join the raid. There were no gps issues before or during the raid. We won but when I clicked the catch button it kicked me out and said gps error so I turned off and on the app again and it didn’t give me the option the catch Mewtwo.
What should I do?
