@rp I am running the supertokens core using docker run command ( I am using aws RDS service for the MYSQL database) . If I uses the core in my single system only, then everything works fine, but the issue arises when the core is also running on other systems. In short I got an Supertokens general error exception when the core is running on more than one system. I don't know why it is showing this strange behaviour.

hey @HimanshuKukreja when you visit the /hello API of the core on your browser, what do you get?

hello in both the systems

right. So the core is working fine

The database is common for both the cores (RDS) could this be a issue??

not really

If I run the two cores in same system (locally) but with different port numbers, it works fine that is my code works properly without any error. But the issue arises when the other core is running on other pc

this might be a network / firewall issue. So im not sure if i can help here
