My default device for the CA is a Samsung Galaxy Note 10+. Until Marcello pointed out that mobile data works, I hadn’t been able to log into my CA in a week or so. I can now log in on mobile data, and use the app normally. However, when I switch to WiFi, it usually falls at or near the first hurdle, failing to show whatever ‘page’ you have asked it to. If I thrash around a few enquiries, nothing loads properly and the ‘Network Error’ will appear within one or two attempts.
FWIW, I also just tried a separate android device (Samsung Galaxy Tab S6 Lite) which doesn’t have mobile data and it works on WiFi with no issues, albeit I’ve only tried it for a few minutes. It doesn’t appear to be affected though.
Sorry I can’t provide more technical information. I’m not an IT expert.
Solution found
My WLAN-router had IPv6 deactivated => set IPv6 on router to “auto-detect”, then disconnected and reconnected WLAN on mobile, and my companion apps works again with WLAN!
(Further infos: In fact, my ISP does not provide IPv6. So I see now that with the setting “auto-detect”, the router uses “6to4 tunnel”, which seems to resolve the problem).
So happy I am back to Companion app. Hope this will resolve the problem for others too.
A big thank you to @Marcello_Gottardo for sharing this workaround method. I’m marking this as a solution to boost its visibility, but please comment to verify whether the issue is still affecting you or not.
If you would like to add any details regarding your ISP or IPv6 capabilities, this could help narrow down a common cause for the issue we’re seeing.
Edit (April 29): If you are still running into this issue, please don’t hesitate to write to us in Support.
Ok, tried restarting my network, still have the error on my pixel 6 phone. Turn off the wifi and use the phones data the app works. Hopefully you’re able to fix the wifi issue soon.
Well, time is marching on with no proper resolution to this. Companion app only functional on mobile data, and not available ‘in game’. For the record, Marcello’s ‘workaround’ solution isn’t an option for me as my ISP doesn’t support IPv6. I’m a Virgin Media customer / victim in the UK and have a ‘Hub 3’ router. It does not have any of the options that Marcello was able to manipulate.
when i open the CA (latest version, maybe the last two) I sometimes have to put in my login and password, or just click the back arrow a few times then i get logged in. Whether I have to do this or not, I always get network error when trying to see other riders signed up in an event. I do have IPV6 disabled on my entire network but this is not the problem. I downgraded my CA to version 3.54.0 and this solved the login credential passing issue and the seeing signed up riders in an event. (no more network error msg). so this issue was introduced in CA versions later than 3.54.0
Sometimes entrant names come up first time on my Android Companion app, but usually for the last 2+ weeks I have to click network error “retry” 3-10 times to get it to work.
you need to first download an old version from a safe .apk mirror be careful many of these try to trick you into installing unwanted software. you could start by googleing “zwift companion app old versions”…then you need to sideload the .apk file.
if you have any doubts as to doing this i would advise against this method.
this is really something that zwift should fix, as they broke it.
by the way zwift, i have read this thread a few times, and see no place where this topic is actually solved.
Hi Rowdy,
Unfortunately, this doesn’t seem to be a solution and is only even a work around for a few folks. Can you confirm that this will still have on the list of things to fix?
FWIW - I get the network error when trying to view the riders in events daily and the login problem intermittently.
Hello @Lebasi_Lashley, thank you for the tag. If you can reach out to us in Support, we’ll be happy to troubleshoot and escalate all relevant information to our engineers. It’s unclear what’s causing this issue, and it does not appear to be very widespread.
It may not be widespread, but there’s plenty of info on this thread showing that it’s happening to multiple people and it might be useful for your engineers to collect info here rather than just collecting my one individual use case. In any case, I have followed the support link (which is a bit cumbersome) and pointed them back to this thread on the forum because that’s where the greatest bulk of information is.
I tried support and the Zwift Ambassador wrote:
“This question should be forwarded back to the advisor because: “Technical Troubleshooting > Using Zwift”. Network error on Companion app.”
Not sure exactly what that means, but doesn’t like help or an answer will be coming from following that path.
It might be helpful if people who’ve commented in this thread would state their phone model and Android version, and steps necessary to reproduce it (if any)
