Page could not be loaded

[rdn]

I just had this happen to me as well, really surprised me. No ad/content blockers, SSL certificate is fine.

Does your site also on Cloudflare?
It happens sometimes here on XF because Cloudflare DNS is down sometimes.

Yes, it is! Interesting.

Cloudflare is congested and overloaded, so quick downtime happens almost everyday :/.
I haven't experience this kind of error on my XF site not using CF.

Just a quick tip. If you are using plesk check the /etc/nginx/nginx.conf file for this;
worker_processes 1;

The default value for this is auto and plesk overrides this to limit the number of worker processes.

I am beating myself up for missing this obvious cause, and am making my shame for missing it public.

Why, oh why did plesk think this was a smart idea?

My advice. Set this value to either auto OR if you have high DB/php load to a value half that of the number of cores in your CPU and adjust from there.

My team just informed me about this error. We are all getting the errors. I personally have 6 computers I tried on, different browsers. Incognito, private windows, you name it- it's the same! Not ad blocker.

Started in the last 24 hours.

Has anyone found a solution? I've been getting this error for two days now and it's really frustrating. I told another person to try logging into the site and they got the same error.

I get that error when i'm rebooting my modem.

Started happening for us in the last week. I'm wondering if it's a cloudflare issue causing connection errors

I just turned off HTTP/3 (with QUIC) in Cloudflare. Seeing if that helps.

Supposedly might be an issue with Safari at times

My forum has been blighted by this for about a week now. I raised a ticket here, sadly got no usable help, and I’m seeing other forums with the issue too. Something is clearly wrong between Cloudflare and Xenforo as it is impacting multiple users, multiple platforms, browsers etc. It is certainly not ad-blockers as I’m getting it hundreds of times on my own site. I run a clean browser (Safari, no plug-ins at all, cross-checked with Chrome, no plug-ins, issue persists).

Here’s a thread on my forum:

‘Page could not be loaded’ error

I’m curious how many folk have been seeing this absurdly non-specific error over the past few days. I’m seeing it a lot, and I know some others are. I’ve no idea what it means. Google gives me nothing tangible. There are no errors in the XenForo admin control panel, no errors at the server host...

Here’s another forum (nothing to do with me) with the same issue I found when researching the error:

ARRSE Not Loading - 28 Apr 26

Been getting this off and on all day. Loads ok when I click the button.

It is clearly a thing. Can we have some help please!

Try turning off http/3.

Seemed to work for me

 

[Tony L]

Thank you. I’ll try that.

 

[Tony L]

I can confirm turning off HTTP/3 in Cloudflare looks to have fixed this error.

Try turning off http/3.

Just trying this out now. Fingers crossed.

I’m wondering why this is happening as of recently? I’m sure I’ve had this option turned on for quite some time now.

Not sure. It started about a week ago. I don’t think a major iOS change happened. Best guess is Cloudflare deployed some http/3 behavior change that impacted Safari.

Yeah, I did only notice it with Safari. As I tend to check out my site on my iPhone throughout the day and this is when I started noticing it, only about a week or so ago.

I logged in to state that this has been happening to our site gbatemp.net too
I will try turning off the HTTP3 option in Cloudflare, hopefully this will help

For anyone looking for the setting, it's in "Speed -> Settings -> Protocol Optimization"

 

[MattW]

I've had multiple reports of this issue as well. Disabling HTTP/3 to see if it resolves it.

Yeah I can confirm disabling that option worked for me! Thanks @arn

I have been experiencing random page not loads with Safari on iOS but, a different/related issue when I tried other borrowers (Chrone and Chrome based Ecosia) . But in that case it was not page not load but loading without any CSS/LESS formatting and js not running. I few days ago I did disable HTTP/3 as @MattW suggested I try in relation to another Mir reproducible CF issue I was having, ie PayPal IPNs failing. I’m still getting those but not had any of the random oage not loading issues.

NB: what I found with the iOS Chrome issue was that it only happened on a page refresh via the browser, not via e.g. going to another or same page via the xenforo navigation. So I could happily tap on New posts repeadly but then a browser refresh would cause/manifest the issue.
