Hi!
I have the same problem (since yesterday)..

In my case, 13 Inputs run smooth, but with the 14th line it breaks..

The only differnce in my case (URL hasn't changed):
I've upgraded from node 6.12.2 to 8.15.1 yesterday.

After the upgrade 2 flot grafics aren't working any more.. Like said earlier, the URL didn't Change, as it is embedded in 3 vis pages..

I have the same problem. After updating Node from 6 to 8. If there are too many lines or too many options.
Is there an explanation or solution?

I'm pretty sure that this has something to do with the url length. In my case I have 12 lines with an url length of 6578 characters. When I add another line I get a 400 Bad Request HTTP error. I assume the maximum allowed url length is usually a setting of the web server or the web framework. Could this be a setting of node or the web adapter of ioBroker?

If course we are far over the recommended max url length. But this is also true for just a few lines in Flot. Modern web browsers should be able to handle more and so it's probably just a setting on the server side.

Ok, they changed the max header size in nodejs v12.6.0+ from 80 to 8 kB:
