justinrh 174 Posted January 11, 2021 Share Posted January 11, 2021 When I browse to http://svr:8096/ using Fx on two of my wireless Windows computers, the page says only "Forbidden". The console shows 403 forbidden. Using Edge works. Another wireless computer has no problem using any browser. The only thing common between the two failed computers is that the OS is 32-bit. The other computers are 64-bit. Clearing cache and cookies do not fix it. The server is also Windows x64. Link to comment Share on other sites More sharing options...
Luke 37088 Posted January 11, 2021 Share Posted January 11, 2021 Hi, perhaps a browser setting or extension? A vanilla installation of the latest version of firefox is working just fine for me in my testing here. Link to comment Share on other sites More sharing options...
Happy2Play 8292 Posted January 11, 2021 Share Posted January 11, 2021 Are all systems on the same network? Have you made any changes on Dashboard-Network? Link to comment Share on other sites More sharing options...

justinrh 174 Posted January 11, 2021 Author Share Posted January 11, 2021 (edited) @Luke Both browsers are vanilla, but have been installed for a long time. And you did use x86 browser, on x86 OS? @Happy2Play Yes, same network. No mods to Dashboard -> Network @cayars Like I said, "the page says only "Forbidden"".

Luke 37088 Posted January 11, 2021 Share Posted January 11, 2021 No, I'm testing on 64-bit. Link to comment Share on other sites More sharing options...
Carlo 4330 Posted January 11, 2021 Share Posted January 11, 2021 Testing for me is 64 bit as well. I haven't had a 32 bit OS in years so I'm not going to be of help. Link to comment Share on other sites More sharing options...
justinrh 174 Posted January 11, 2021 Author Share Posted January 11, 2021 Can you install the 32-bit version of the browser? Link to comment Share on other sites More sharing options...
Happy2Play 8292 Posted January 11, 2021 Share Posted January 11, 2021 (edited) I had no issue installing FF 84.0.2 (32-bit) and opening Emby. A guess would possibly be a Windows user profile issue. If you login in with a different user does the same thing happen? Are you sure all clients are on the same network?

pwhodges 1532 Posted January 11, 2021 Share Posted January 11, 2021 So Edge works and Firefox doesn't. I would start by looking very carefully at the security settings in Firefox. Then the Windows firewall - perhaps Firefox doesn't have permission to connect to non-standard ports. Is there any other security software installed that might restrict networking - these things do get mentioned here from time to time.

Solution justinrh 174 Posted January 11, 2021 Author Solution Share Posted January 11, 2021 (edited) I found the problem: IPV6! I turn off IPV6 for the NIC and Fx can connect! Also, the problem is not unique to Fx x86; I found a x64 machine that did the same. Any theories on how IPV6 causes a problem in this case only for Firefox?

Happy2Play 8292 Posted January 12, 2021 Share Posted January 12, 2021 There was another topic somewhere but ipv6 was not considered a Local network and did this exact same thing until it was added to Local Networks. So your network is/was a mix of ipv4 and ipv6 address then. I Link to comment Share on other sites More sharing options...

I'm not sure what you are saying. Fx worked otherwise, so somehow IPV6 was being invoked (I guess) only for that address or port #. The issue didn't affect Edge. Is this 'local network' setting you are talking about at the OS level or in the browser? Do you know how to configure such? (I don't see anything specific to IPV6 in Fx settings.)

Happy2Play 8292 Posted January 12, 2021 Share Posted January 12, 2021 In Emby Dashboard-Network, Local Networks (still looking for previous topic) LAN networks: Comma separated list of IP addresses or IP/netmask entries for networks that will be considered on local network when enforcing bandwidth restrictions. If set, all other IP addresses will be considered to be on the external network and will be subject to the external bandwidth restrictions. If left blank, only the server's subnet and common private IP subnets (10.0.0.0/8, 192.168.0.0/24, etc.) are considered to be on the local network. But it still does not make any since if other browsers work and only Firefox doesn't in this environment, but hey every browser does their own thing so who really know. Do you have "Allow Remote access" Disabled? If so and you enable it do you still see this issue? Link to comment Share on other sites More sharing options...
Happy2Play 8292 Posted January 12, 2021 Share Posted January 12, 2021 Also what url are you using? Have you tried the actual ip displayed on the dashboard? Link to comment Share on other sites More sharing options...
justinrh 174 Posted January 12, 2021 Author Share Posted January 12, 2021 Okay, you have exposed some things, @Happy2Play. With "Allow Remote access" enabled, it works. (It was disabled.) If I use the TCP IPV4 address in the URL it works. (I had been using the server node name.) Link to comment Share on other sites More sharing options...
Happy2Play 8292 Posted January 12, 2021 Share Posted January 12, 2021 Possibly disable ipv6 in Firefox Firefox can't load websites but other browsers can | Firefox Help (mozilla.org) 1 Link to comment Share on other sites More sharing options...
justinrh 174 Posted January 12, 2021 Author Share Posted January 12, 2021 Awesome, that works also. You'll need a whole FAQ page just for all the different ways to work around IPV6 issues! Link to comment Share on other sites More sharing options...

roaku 795 Posted June 9, 2021 Share Posted June 9, 2021 I was having the forbidden issue in Firefox with the .local pseudo domain. Turning off ipv6 resolved the issue for that too. 2 Link to comment Share on other sites More sharing options...
