Weirdly, this error cropped up today 'Your IP address does not match this session'.

I have deleted my browsers files, cache, cookies - the lot. No difference, I have tried alternative browsers on my laptop and I have the same issue. So I tried logging in via my mobile and I managed to get in (this is on the same internet connection as my laptop). I've restarted my machine and I'm still unable to bypass the annoying message.

In the end I enabled 'Trust IP addresses provided by proxies?' via my mobile and I was able to proceed, however I am a little unsure if this is actually safe to do. I don't get why all of a sudden my sites having an hard time with this, it seems a bug but I am unable to find anything searching it and I am currently unable to renew this sites license (due to Christmas). It's a bill I would rather avoid considering, so I'm hoping someone might be able to assist me.

I've never experienced this at all, no issues what-so-ever.

I can't locate 'clearsessions', not even by searching it.

Thanks for trying to help, this hasn't resolved it for me but was worth the go.

See this guide

I'm having this same issue. It happens frequently and is very annoying. It seems to only affect me when i have an ipv6 address. I don't want to disable ip checking but would think that it would work with ipv6 as well.

Have a look at this. It might help.
