OLS on GCP (GoogleCloud) + Wordpress - i lost connection

Brothers,i need help

I have installed OLS on GCP (Google Cloud Platform) with 3x wordpress there setup by ex IT specialist.

By mistake I installed again package with OpenLiteSpeed... and it's look like it lost SSL certyfication.

It show me: "You cannot visit portal.fonia.app right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later."

How can i bring it back?
Or download backup of wordpress and move to diffrent hosting?

Thanks in advanced!
