Inside a Vue component, I run multiple instances of Etherpad editor which are embedded in iframes. Below is an example of that component-

Etherpad.vue (A page component)

<div>
  <iframe src="https://mydomain.in/p/1505-g4Q?token=uuid&userName=jo&userColor=%23ffc7c7&rtl=false&lang=en"></iframe>
  <iframe src="https://mydomain.in/p/1506-g4Q?token=uuid&userName=jo&userColor=%23ffc7c7&rtl=false&lang=en"></iframe>
  <iframe src="https://mydomain.in/p/1507-g4Q?token=uuid&userName=jo&userColor=%23ffc7c7&rtl=false&lang=en"></iframe>
</div>

Now, I prepare a URL for this page suppose its, https://mydomain.in/etherpad/collaborate and share it with others to collaborate on this page. Each user who has access to this URL can type inside these three editors.

The issue

If only a single user is collaborating on this page, things are fine. As soon as other users started working on it, each user is having the following popup of disconnection-

enter image description here

And once a user clicks force reconnects, it appears on the other user's side which is resultant to allow only one user to type at a time.

Environment

vue: 2.6.11
node : 13.14.0"
Etherpad version: 1.8.16,
Web server: Nginx
Browser: Chrome
Authentication: Custom JWT verification (can see in iframe URLs)
Etherpad database type: postgress (database is hosted on a separate machine)

  • Etherpad client and Vue are being served on the same domain to avoid the cross-domain cookies, and cross-domain embedding issues.
  • I am serving Etherpad behind Nginx reverse proxy. On the root path ('/') I serve the Vue application and on /p/ path requests, I pass them to the Etherpad node server.

Things I tried to debug

  • Tested locally, one user in Firefox and another in Chrome, working fine.
  • Tested with two users with different IP addresses, giving a disconnection popup.
  • Some answers say to look into the settings to alter the connection limit but didn't mention which settings.
  • For some users, this issue occurs when pasting a long text but for me, it's happening even when typing a single sentence.

Any help to suggest where to debug or which settings to change even in code or at server configuration would be great.

    Not an answer, but rather direction for further debug - check browser console (Ctrl-Shift-C in Chrome) and network events when this disconnection is happening. This may give more clues to what is going on. – mickvav Jan 29 '23 at 23:58
  • Hey, thanks for the response. I tried it already but couldn't find any relevant error message. Still, I'll give it one more try. – Neha Soni Jan 30 '23 at 03:57
