Some users getting connection difficulties to an endpoint proxied by a LoadBalancer

What is the name of the domain?

graph-gateway.graphops.xyz

What is the error message?

ERR_SSL_PROTOCOL_ERROR

What is the issue you’re encountering

A very small number of clients report this error, from different geolocations. Works fine for them if they turn on a VPN

What steps have you taken to resolve the issue?

Looked for records of failed connections - none to be found
Verified all that I could (DNS and TLS settings), all seems fine

What are the steps to reproduce the issue?

Hard, seems to only affect a very small % of users from different locations, haven’t been able to reproduce in any environment controlled by me

It’s ready to roll and works fine from my end at least:

Might be related due to your SSL/TLS settings at Cloudflare dashboard for your Website. Otherwise, a local DNS resolution issue.
