In the last couple days I’ve started getting a lot of “Invalid Frame Header” errors, anyone else getting these? I’m not entirely sure how to debug this, it looks like it might be related to the connection upgrade.
You can see them here anara.farm it seems to happen around the 5th or 6th page load, it’s very random though.
of course today they don’t seem to be happening, this leads me to believe its a 3rd party interference problem e.g. internet, cloud provider etc… I’ll keep you posted if I find the cause
By the time I was about to check the website (looks really nice!), you had already posted your own answer 
Never seen those errors myself, but I will keep an eye out for them.
