The webcam stream in octoprint won't show and keeps loading, but it shows in Cura's octoprint connection extension
Stream url: "/webcam/?action=stream"
I tried changing the stream url, but that didn't work

**Camera model**
**What is the problem?**
**What did you already try to solve it?**
**Logs** (`/var/log/webcamd.log`, syslog, dmesg, ... **no logs, no support**)
**Additional information about your setup** (OctoPrint version, OctoPi version, ...)
and please post the webcam url you have currently configured. Hard to tell what's wrong with it w/o looking at it.
Ok, I fixed it, hope it helps!
Ok, I added more detail, hope it helps!
Unfortunately you left out the log file asked (i.e. /var/log/webcamd.log). And that's assuming you're using OctoPi, if not then you should know where that log file lives and how to retrieve it.
I don't have anything helpful to add, but as the creator of the OctoPrint Connection plugin it is nice to read that my plugin is doing something right that does not work in OctoPrint for a change 
Im running octoprint on a old acer laptop, running linux, I have set up jpeg streamer properly, and when I go to MyIp:8080 I get the mjpeg streamer webpage, and it gives me a still image too, but when I click the "Stream" button, the page keeps loading forever
Sorry but I still have a bunch of questions to better understand the issue:
Which distribution? Ubuntu, Debian, Fedora, CentOS, ArchLinux, Alpine Linux, other? Which version? Is the laptop connected to WiFi, or through an ethernet cable?
Do you have HAProxy or another reverse proxy set up? Otherwise the streaming URL you've provided shouldn't work... If so can you also provide the configuration file you used, and the program version?
What are the streaming parameters you've provided to mjpg_streamer? And how do you start it? Systemd service, other? If so you should have a log of the output of mjpg_streamer that you could post here.
Ok got it fixed, it was a firewall on my computer, so it was my computer not octoprint. Once I removed the firewall, it worked perfectly!
