Apologies if it's been solved in a PP, but if not, clear the cookies in your browsing history.

I think we have all done that several times.

I still can't use MN on Chrome on my Android phone. It's been about a week now. I have cleared my cache etc etc. I can use another browser or incognito mode (although that's a bit slow) but it's a pain.

ThaneOfGlamis · 10/05/2026 20:20

Urgh, this happened to me yesterday. I did clear the history, but as it then logged me out of everything, I spent ages logging back in and changing passwords that I couldn't remember. So annoying.

Problem still not resolved

Ludmilaandthelonely · 10/05/2026 09:11

Glad I found this thread. Must admit this is reducing my MN use because I really don't like the app.

Livelovelaughfuckoff · 10/05/2026 09:03

I can’t use mumsnet on anything now other than private browser and even then it’s hit and miss and slow to load most of the time. Not a new problem either been this way for months. Shame was always a great resource. The website is a complete pile of shite now.

It’s laughable that MNHQ’s only offering of a solution is one that causes inconvenience to its users. I’m not clearing my cache and going through the faff of having to sign back in to everything else I use. These problems have been going on so long it’s clear there is no intention to solve it really.

I have the same on my android phone when using Ecosia for the last week or so. I can access the site using Chrome but I dont like to use it and so am using mumsnet much less frequently - it was daily until this issue, now I check every 2/3 days. Please @KellyMumsnet @BeckyAMumsnet can something more be done. I have cleared cache numerous times, restarted phone etc. Using a browser not the app

ManufacturedConcerns · 09/05/2026 21:02

Finally got it to work by clearing everything for the last 7 days. So once again I've been signed out of all my websites. It's not good enough. And if there's a way to only clear the cache etc for Mumsnet then I can't find it.

TutTutTutSigh · 09/05/2026 20:49

First time I've been able to log in for 4 days, sort it out please! Clearly not a user issue when mumsnet is the only common denominator.

ManufacturedConcerns · 09/05/2026 17:48

Ive cleared my cache again. Deleted browsing data etc etc. Still not working.

Theunamedcat · 09/05/2026 16:10

its unusable and completely inaccessible in my phone now ive taken the steps and error after error

Hello @IDontHateRainbows we do appreciate the hassle involved. Unfortunately this appears to be a browser-side issue rather than something we can fix from our end. You should be able to clear the cache just for Mumsnet, though, which means data for your other sites should remain unaffected.

There are instructions on how to do it by device here: www.mumsnet.com/talk/site_stuff/5522378-update-on-recent-404-errors-and-how-to-clear-your-cache?

I don't believe it is browser side as many of us have followed the instructions and still not got it to work.

When I initially googled it said that if none of these steps work then it must be the website that has an issue.

WallaceinAnderland · 09/05/2026 14:25

I didn't need to clear anything.

IDontHateRainbows · 09/05/2026 12:45

Its a pain accessing on incognito as I have to keep coming out of incognito to access other sites I'm logged in on. Then back to incognito for mn. Any update @BeckyAMumsnet @KellyMumsnet on whether this is being sorted. Don't want to clear my history and have to log into everything again and nor should we have to.

Younginside · 09/05/2026 08:24

Mine is working again for me, but only after clearing out all history, cache and cookies from Samsung browser. I have lost all my stats for various games that I play which may cure my addictions so perhaps that's not so bad. But it points to MN having unreasonably large elements (at one point the 400 message confirmed something too large to load).

ChristmasStars · 09/05/2026 08:03

So glad I found this thread. I've had it for days and I've followed all the steps. Now I can only access MN on chrome incognito but you always have to sign in again.

It's only MN.

WallaceinAnderland · 09/05/2026 01:32

I had 404 message on chrome tonight for about an hour. Resolved now.

HappyTalkingAndLaughing · 08/05/2026 22:19

Also getting the 404 message on my Android mobile. Have cleared out search history etc many times over the last few days

It might work on chrome if the problem was with edge

Having downloaded Chrome, yes that works. Thanks.

We're all incognito now. Never mind MN, more MI5.

I've manged to get here by using an incognito tab
