400 bad request

[MJMG2015]

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?!

@DDIJ

I've been getting that for ages. I thought I was banned at first.

I'm glad you weren't. 😊

I probably should ban myself though! I get a LOT more done when I can't access MN 🤣

Oh me too I thought it was just me

It's on my phone for me. When I go to the website

Hi OP

Could we have a screenshot please? And could you let us know what emails are doing this?

@LilyMumsnet

Emails - just checked all of these!
'you've been mentioned'
'Someone has posted on' (New message on thread)
'Check out there updates on AIBU POLL'
Trying to click on a link in an email from MNHQ re a deleted thread/post that I've reported

Every email!

Is that shot ok?

Just to add it's not just emails. When I go into Mumsnet from Google the last couple of days it's sometimes done that. I've not been able to get back on for a few hours.
And yesterday it wouldn't let me on late evening and I couldn't get on till a couple of hours ago.
But on my laptop it worked

Yes, as I said in my OP, I can't go in through my browser either (which does happen to be google & I've no intention of changing it)

Hi @MJMG2015 are you able to send an example URL so that we can hopefully get to the bottom of this for you please?

Hi @purpleme12 are you still experiencing problems too? Are you able to send an example link please?

Hi @DDIJ sorry to hear that. Are you able to send an example link please?

@soniamumsnet I haven't had it for a couple of days I don't think

@soniamumsnet

Hi *@MJMG2015* are you able to send an example URL so that we can hopefully get to the bottom of this for you please?

Is this what you need?

Hi @DDIJ if you could email us at: [email protected] that would be really helpful. Thanks.

Yep me too. This has gone on for weeks. I can only get onto the site via Chrome which Ive had to load separately onto my mac

It does this

Thanks @HasaDigaEebowai we're taking a look into this issue and will hopefully have some more information for you soon.

How is what Hasa posted different to what I posted on the 8th?

I just checked & it's still doing it and as I said before I don't want to change to chrome on my iPad. Loads of us did that once before, but then MN sorted the problem out.

Hi @MJMG2015 just to let you know that we're still investigating and will let you know as soon as we have more information.

Thanks. No worries - It's ok on my phone. Thank God!!!

Have a good weekend

Try a private browsing window. If that works then clear your cookies.

Why?

"Bad request" is when your browser has made a request that the server can't handle. The usual cause of this is because the request is too large, and the usual cause of that is when your cookies get too big - cookies get sent with every request. If the site has crappy adverts and tracking or a bug or page that causes data to be continually added to your cookies, then eventually the site will stop working for some links and not others (depending on how long the link is - longer links won't work).

tl;dr clear your cookies.

@soniamumsnet

If the problem is cookies, then it's an absolute pig of a problem to fix for users without instructing them to clear their cookies, which is impossible to do if they can't visit the site anymore.

I recommend temporarily increasing the maximum request size and logging out requests that are larger than the old maximum, then identify the broken pages that are causing the problem. Then fix that page, and at some point in the future (ideally after the poisoned cookies have all expired) decrease the limit again.

You could also make the 400 error page deliver "set-cookie" headers for the broken cookies with an expiry date in the past. Then users would see one more error and they'd be allowed to log in again. But either way, it's gonna need someone pretty technical with system level access to fix.

Good luck!
