On my iPad I keep getting this whether I try to go from a message in my email OR IF I type the address into my browser OR try to go via 'most visited'

It's been Happening for a couple of weeks now. Fortunately it's fine in my phone.

Any suggestions?!

@davidsong Thanks

I'll give that a go tomorrow.

Hi, just popping in to see if anyone can try accessing the site from other devices/browsers and let us know which devices/browsers are showing the error please?

Also, can you let us know if you are accessing the site using wifi or 3g/4g please?

@soniamumsnet

Sorry I didn't realise you'd posted!

It's fine on my iPhone (safari). Not on my iPad (also safari)

Wifi. Both.

I dot suppose that helps much. Sorry.

Works with app on my phone. Not working on chrome since about an hour ago

Sorry forgot to say I'm using WiFi

Did you try a private browsing window?

Can access site on phone but not on desk top.

I’ve had this for weeks - only accessible using a private browser

Using an iPhone/safari

www.mumsnet.com/Talk

Ok using Edge but not Chrome.

Sort it out, MN. :)

Just started happening for me today. Fine in my phone but not on my laptop.

Hi, sorry you're still having problems. Can you let us know if you are accessing the site using wifi or 3g/4g please?

This is happening for me today (and it has done sporadically in the past, so I think this is an ongoing issue).

I'm using Chrome on a Chromebook and Wifi.

Can connect using a private browsing window, but not a regular window.

@soniamumsner if private browsing works but a normal browsing doesn't, then it's definitely cookies.

To fix it in Chrome:

1. Click the dots menu in the top right corner of the browser.
2. Select settings from the drop down menu
3. On the left, pick "privacy and security" then click "cookies and other site data" on the right.
4. Scroll down and choose "See all cookies and site data" to get a list of all your cookies
5. In the "search cookies" box, type "Mumsnet" - you should now see two listings - "www.mumsnet.com" and "mumsnet.com"
6. Click the dustbin icon to the right of both of those listings.
7. Go back to the site and log in again, it should work fine for a while until it happens again.

For Mumsnet HQ developers: your "FCCDCF" cookie is holding a great big cob of JSON data, including a list of lists. Your "mnfmt" cookie is holding reams of base64 encoded guff. These two are the most likely cause. Either increase your max http request length or stop writing cheques you can't cash!

For Safari on iPad/iPhone

Clear the mumsnet.com ones.

I am using WiFi @soniamumsnet

Thank you @davidsong - all fixed now!

I am gettting this message since yesterday (29th September) on Microsoft edge.

Works fine in IPAD And firefox browser.

I keep getting this on my laptop using Chrome today.

If I delete my Mumsnet cookies I can get back in again, but the same thing then happens just a few threads later and I then need to delete the cookies again.

@MNHQ I'm getting this on my phone since yesterday (android, chrome, mobile site). I've cleared cookies as per the instructions above but it's still not working. I can load "active convos" but the error occurs when I try to open a thread.

(PS, it works fine in my phone if I use incognito mode)

Still can't get on using chrome, despite clearing cookies.

Any progress?

In Chrome mobile it's dots menu in the top right corner, settings, site settings, all sites, click magnifying glass, search for Mumsnet, delete them.
