Looks like something is wrong with the signing keys. If you're ok with resetting them, you can clear the tc_keystore table.

Thanks for the answer, but I have a question, if I make an alter table tc_keystore, will it somehow affect the operation of the system and will the data be lost or not? because I have over 300 cars with data

Data won't be lost, but old API tokens will be invalid.
