Error 100056000 on home network with only one device

Hi all,

I and several of my coworkers are having issues logging into zoom and starting meetings. We all have similar symptoms to:

1. Our work laptops cannot connect to `<company_subdomain>.zoom.us`
2. We can connect to `<company_subdomain>.zoom.us` from other networks on our laptops
3. We can connect to `<company_subdomain>.zoom.us` from other devices on the **same home network**
4. The error code we receive is 100056000 with no information

5. If we start the meeting from a different network (like tethering via our cellphone) and then switch to the home network, the meeting stays open without error

Troubleshooting steps already tried:
1. Reinstalling Zoom

2. Clearing all cookies from browsers
3. Uninstalling Zoom, removing all app data (using `find / -iname "*zoom.us*"` and deleting all results), restarting computer, then installing from a fresh download

All yield the same result, same error code.

We do not use VPNs and have already disabled anything messing with DNS on our networks. This seems to have started around Nov 7th, 2022.

The issue is present across several macOS platforms, Intel and Apple Silicon

Any help is appreciated, thanks!!

Hello @jaschwar,

This could be a network issue with your firewall or proxy, or it could be a IdP issue with the Identity provider your organization is using to integrate with Zoom. Please check both and let me know if there is anything that I can do to assist you with this issue.

SSO/SAML documentation

Thanks,

Thanks for the reply @YaBoiB !

I've checked and everything seems to be in place for those items, but I'll go back over and talk with our security folks to see if they can find anything I can't.

In the meantime, are there any logs that I can enable to get a better understanding of the error? It's pretty generic.

Thanks!

Hello @jaschwar,

Unfortunately, the logging that we have is encrypted, so you would need to open up a Support ticket with our Technical Support Reps and then send a problem report from the client. Our Support team will then work with our Engineering team to determine the root cause. There are some logging on your local client under the "AppData" folder that you can look at but I am not sure if these logs will provide you with the full picture of what you are looking for.

"The new app will be available for installation through the Google Play Store, a practice that started last year, as well as being available to install from the web directly as is offered by many other PWAs."

I have this exact same issue that @jaschwar did such an incredible job detailing. I have worked with Mac/Apple for months on this and all roads lead back to Zoom who has been absolutely NO HELP in resolving this now growing issue with error code 100056000. Zoom please help!

Did anyone ever get any assistance with this? I've been having the same issue for months. My MacBookAir with M2 connects fine. My iMac with Intel gives me the 100056000 error, which searching tells me is an issue with Chrome Books, but clearly is not my issue. I've got a support ticket set up and I've been going back and forth with zoom since the end of April and no one has been able to fix the issue.

Issue has not changed! I can get on Zoom with Safari at least, to cancel my account. I still can't get on Zoom on Google Chrome and have had to use my phone (terrible Zoom experience on Smart phones!). I'm so frustrated. I've sort of given up because when I think about it it burns me up inside. Have convinced my work group to switch to Google Meet...

I've been struggling with this issue for a while. The particular symptoms for me were that as soon as I would log into Zoom, the requests to zoom.us would stop getting through, whether through the browser or through the app. Clearing browser cookies would solve the issue in the browser, but I was never able to get the app working properly. I finally tried changing my internet connection. It seems that CenturyLink is the source of the problem for me. I first tried tethering to my phone, which worked, but isn't ideal for video calls. I then tried using a VPN (I used ProtonVPN). With the VPN on, Zoom works fine. I tried reporting this issue to CenturyLink, but the tech pointed the finger back at Zoom, so I guess I just have to use a VPN to get Zoom working here.

tldr; Try using a VPN

My struggle is that I have multiple devices connected to the same Centurylink connection, and only one device doesn't work. Four of them are accessible in the same office. Of course, it's the one that I need to be able to do my job and hold a Zoom meeting accurately, but I don't understand how Centurylink is the issue if it's just one computer that won't work. So what you're saying makes sense but also doesn't, haha.

I don't get it either. It is technically possible to filter out a particular type of connection for a particular device like that but *why*? All I really know is that I was able to get it working by connecting through a VPN. I don't love the solution but at least I can do what I need to do now.
