Scalar: Etherpad widget broken on all platforms "Sorry, this content is not embeddable in Matrix"

[aaronraimist]

Starting in the last day or two I've seen people report that the Etherpad widget is broken on Android and iOS and I can reproduce on web.

@jaywink this still works for me - any ideas?

[jaywink]

It looks tbh either a temporary problem with Scalar or Etherpad itself. I can't really tell where the 502 is from in the stack. Could dig deeper but first would like to ask @aaronraimist can you still get a failure? If so, can you let me know the timestamp when you re-tried and I will take a new look at logs?

For me tried web, desktop and mobile, not live and develop, and things seem to work fine atm.

[aaronraimist]

Hmm. No I cannot reproduce it today. I'll reopen if I get it again or hear any more reports. It seems like it was broken for about a 24 hour period before I opened this issue though so it may be worth looking in to those logs.

I have this exact & reproducable behaviour when I use etherpad names that are too long: ABCDEFGHIJKLMNOPQRS as pad name, i.e. 20 chars long works just fine, but ABCDEFGHIJKLMNOPQRST, i.e. 21 chars long, results in a 502 bad gateway and the not embeddable banana. Could that be what was actually causing this? Related: https://github.com/vector-im/riot-web/issues/6039

A friend of mine has a slightly different issue:
She has an issue with Etherpad - only on the Mac. Elsewhere (iPad, iPhone) she can open the integration just fine, but on the Mac she gets this content is not embeddable in Matrix. both in Safari and in the installed Element Desktop.
On the iPad it crashes sometimes, but otherwise works well.

Yes I can confirm that this is still the problem on Safari or Brave and in latest (1.7.16) Element.app on macOS Big Sur 11.1
Element.app:

Safari.app:

Brave.app:

As much as I don't trust Google Chrome.app for my daily browsing I decided to do a last test and turns out it is the only one that works:
