Netflix stopped working after upgrade to 1.11.917.39



  • After the latest upgrade (1.11.917.39) Netflix returns a unexpected error occurred message, with error code M7121-1331-P7 when I try to watch a movie/tv show. I don't have any problem logging in automatically, and the initial screen (listing stuff to watch) is displayed okay. I don't have any problem watching Netflix using Chrome 60.0.3112.90 (Official Build) (64-bit) or Firefox 54.0.1 (32-bit). I'm using 64-bit Windows 10 Home version 1703 on a PC with a Intel i7-3770 and 16GB of memory, using the built-in graphics (no graphics card).

    I called Netflix help and all they would do is tell me is that the error code meant the browser was unsupported. I'm using the same settings that worked before the latest update. I checked that the user agent string still identifies it as Chrome. I have a ublock origin, privacy badger, cookies and advanced font settings extension. I can stream video using YouTube okay.

    Suggestions?



  • I bet that if you use an User agent switcher like
    https://chrome.google.com/webstore/detail/user-agent-switcher-for-g/ffhkkpnppgnfaobgihpdblnhmmbodake?hl=en
    it will work if you set it to fake Chrome's user agent.
    Tell the people at Netfilx they have to make a better User Agent detection because it's due to bad coders like theirs that Vivaldi is still not recognized as a valid and updated browser, and instead Vivaldi team has to fake the user agent in different ways in different sites.



  • @emoore NF still streams fine for me here with 1.11.917.39, so maybe it's specifically only a Windows thing, or maybe something with your profile?



  • I get the same exact error message on Netflix since the browser upgrade, too. It worked fine before. I tried the user agent switcher extension and set it Chrome for Windows, but then when trying to play something, Netflix asks me to install Microsoft Silverlight. I tried that, and the installer tells me I already have a newer version installed so it won't do anything. Same result if I set the user agent to Firefox, so switching the user agent is a no go it seems. Netflix works fine on regular Firefox and Chrome. I'm also on 64 bit Win 10 Home.



  • I'm also getting the error message today but I'm pretty sure I was watching Netflix yesterday with 1.11 and not having any problems then. So I wonder could Netflix have changed anything and not a problem with the upgrade?

    Changing the user agent gives me the same problems as @iridescent with asking me to install Microsoft Silverlight. So... it looks like I need a separate browser for Netflix for the time being. :rolling_eyes:

    I have contacted Netflix support about it via chat, they do seem to be very aware of Vivaldi, knew exactly what I was talking about, and they said they will be sure to pass it on - I'm not holding my breath but I think this is the best thing we can all do - if enough of us report it and explain that it was working perfectly fine with no compatibility issues until now, they might take notice.



  • Same here. It was working yesterday morning with 1.11 but later at night... Not anymore. I thought it might be a problem with netflix or something but it's still not working. So... it's weird.

    Windows 10 Pro 64-bit here, last update.

    I installed the user agent switcher add-on, updated the google chrome for windows settings to use the user agent from my installed copy of Chrome, and selected those settings. Same problem. I also closed and re-opened the web site in case it was using a cached version of the user agent string.

    I used Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.90 Safari/537.36 as the user agent string which I obtained from http://browserspy.dk/useragent.php



  • @iAN-CooG

    I filed a bug report. I included my email address in case they needed to contact me. They didn't provide a bug report number or a link to the bug report afterwards.

  • What's the matter?



  • Hello I have the same problem, same error. It happened as soon as I updated my copy of Vivaldi to 1.11.917.39. I chatted with a Netflix customer support representative. She told me they don't consider Vivaldi a supported browser and to switch to Chrome. I asked to have Vivaldi whitelisted by the people in charge, but she seemed to be following a script and kept repeating the same line about switching to a supported browser. It's like I gave her the excuse she needed. Also the agent spoofing workaround didn't work for me, but before the update Netflix was working fine. I don't like having to switch browsers for this one app but I am stuck.



  • @cargo "I don't like having to switch browsers for this one app but I am stuck"

    I suppose then any suggestion of a platform switch would be also unappealing to you? NF continues to be fine in Linux. :-)



  • Nah I find it silly to poke fun at other people's computer related choices. I am sure it will get fixed, just a shame Netflix doesn't think much of Vivaldi.

    As it was apparently unclear to you, i was not poking fun, i was sincere. Migration is possible, if one has a mind to try it. I know; prior to my late-2013 "discovery" of Linux, & 6 months of careful learning & testing in 2014 H1, i realised that my 20+ years of MSWin usage had no further justification, so i migrated in 2014 H2. That's all boringly irrelevant to you, other than the fact that i'm illustrating to you that leopards actually can change their spots after all.

    I got the same initially but challenged it - I told them that it was working fine until now, that there's no technical reason for it to not work, and that any compatibility issues should be my own responsibility to look out for and not theirs. She went away for a bit and came back a lot more responsive... almost as if they put someone else on who knew what they were talking about (of course I don't know this)! She even offered to go through some troubleshooting steps that might fix things in my Vivaldi installation, with no guarantees - I was very time-constrained by that point so I'm afraid I had to decline, I have no idea what they were planning to do and have doubts that it would have helped but I was quite surprised (it would have been interesting).

    So yeah, be polite but don't take no for an answer, that would be my suggestion.



  • How to resolve?



  • I don't recommend users install user agent switcher. The plugin was bought out recently and now poses a huge security risk as it sends browsing data and activity to a website and includes malware. More info here: https://news.ycombinator.com/item?id=14889619



  • This just further proves why my request for a native user agent switcher is needed i strongly encourage anyone frustrated with such issues to hit that upvote button please for the good us all https://forum.vivaldi.net/topic/20037/feature-requests-for-1-12/105
