Debugging Login Issue for Laravel Website

We're experiencing an issue with our Laravel website. The login works intermittently for regular users, and I've noticed this issue on Google Chrome. The problem seems to happen randomly without any specific pattern. When it fails, after login, php log says the user has logged in. But in the website, it shows that the user is still in unlogged in mode. It seems the login state is not properly for the website either in the cookie, or somewhere in the webpage

Key Points:
- Occurring for regular users on Google Chrome
- Random failures without a pattern

I'm looking for a skilled Laravel developer who can help me diagnose and resolve this issue.

Ideal Skills and Experience:
- Strong proficiency with Laravel PHP framework
- In-depth understanding of backend/frontend synchronization
- Previous experience with debugging login/authentication issues
- Familiarity with handling cookies in a secure manner
- Excellent problem-solving skills and attention to detail
- Ability to effectively communicate technical information to non-technical personnel

The work has to be done remotely using remote control software like TV or anydesk

Your help in fixing this issue would be greatly appreciated.
