Why doesn't it let ocStore 3.0.3.7 into the admin panel?

Question

PHP

Good evening, help me solve the problem. For no apparent reason, it does not allow access to the admin panel to the online store on the ocStore 3.0.3.7 platform. That is, we enter the username and password, and that's it, nothing happens further. We restored the backup, it works for two days and the same problem with the admin panel.

There is an assumption that this is due to the fact that I set the settings to the local time of New York. Since we are developing a store for America.

Please tell me how to solve this problem???
