I need to re-Log-in all the time

Hello.

I make a successful login through STEAM in

https://www.pathofexile.com/login

with the lock checked in (remember me)

after that for some time (literally half an hour maybe less)

I can use

https://www.pathofexile.com/trade2/search/poe2/Standard

make requests through in the game itself to quickly find out the price of any product.

I use this program to make requests to POE2 -> https://kvan7.github.io/Exiled-Exchange-2/download

but after a short time my successful login is no longer valid and the UI tells me to log in again.

previously a successful login was valid for a very long time.

what am I doing wrong, any info please?

Thank You !
Regards,
Anton.

I had this frequently and the cause was the internet connection my end. We were double NATing. (Network Address Translation)
Try using a more direct internet connection if possible and see if it makes a difference. If you connect though a hotel, or university or similar shared internet service this might be the cause.
