Hi, I had an online-shop that I copied with the duplicator plugin. Removed Oxygen as well as some other plugins and installed Bricks and rebuild the site. I know it’s recommended to start on a fresh install but I wanted to keep all my WooCommerce data and settings.
Now I’m getting awfully often this error message. After reloading the page, it often works again.
This site can’t be reached
The webpage at https://fonduelivery.de/kasse might be temporarily down or it may have moved permanently to a new web address.
ERR_HTTP2_SERVER_REFUSED_STREAM
Also the plugin WooCommerce Paypal Payments gives out this message and orders are not going through anymore.

I thought maybe someone came across a similar situation and has some advice for me, thanks!
