Hi,
I can’t log in to the Kirby Panel on a live server – when I enter mail and password, it just turns red and doesn’t log in. My credentials are definitely correct and I’ve tried with different accounts. I’ve successfully used the panel yesterday night and haven’t touched anything since. I’ve tried with Chrome, Firefox and Safari. Any Idea what the issue might be?
All the best
in the console I get an error message from https://website.com/api/auth/login:
{status: "error", message: "Invalid CSRF token", key: "error.invalidArgument", details: [], code: 400} code: 400 details: [] key: "error.invalidArgument" message: "Invalid CSRF token" status: "error"
Check this thread/post: Can not log in to panel - Invalid CSRF token
Just realized this is the case with another page hosted with the same provider, I guess they must have changed some settings overnight? This is so strange!
How can I find out what my server returns like in the post you linked?
This tells me to enable javascript in my browser, although javascript is enabled? 
ah, wrong tab, still weird…
the set-cookie portion highlighted in the post from the other thread looks similar:
Meanwhile, I’m chatting with the support of one.com but they aren’t of any help. They created a support ticket and will get back to me if they find out anything
We have another issue with Kirby 2, but also one.com, other issue, but still…
Ah, seems you have Varnish cache enabled. Wonder if that might be the culprit?
I can see Via: 1.1 varnish (Varnish/6.2) on the other site as well.
I’ll try to disable it. I have no experience with this whatsoever, do I understand correctly that I have to add the line in my main .htaccess file?
Yes, try to put this at the top of your .htaccess.
I still can’t log in and it still says via: 1.1 varnish (Varnish/6.3)… gonna start another chat with the one.com support
they said they’ve deleted the cache on my request and even though it still says via: 1.1 varnish (Varnish/6.3) , varnish itself should be disabled. still can’t log in, so this unfortunately doesn’t fix the issue 
Hey; I have the exact same issue!
And whenever I reload the page, this code is showing up for a sec; I don’t know if thats relevant.
Deleted the cash, reinstalled, but still…
i remember the first time the login failed, a “fatal error” message was flashing, but I couldn’t read if it was the same one…
are you also hosing with one.com?
Yes haha; but they told me they’ve changed nothing. I don’t care, but my clients want to edit on my server; I have a subfolder with Kirby for each website.
one.com was super nice, but now its so strange.
