We are self-hosting a webflow-generated page and are experiencing issues running the Google Pagespeed and the GTmetrix reports. Both are generating errors. There appears to be issues with preconnect and LCP.
GTmetrix tends to fail if your webpage doesnt have much on it and returns 0 values. This is not the case for your webpage but I thought it was useful.
I managed to crash lighthouse test to show issues.
See image.
As you can see the page never finishes loading and causes a different crash on pagespeed index.
