My site has been working properly and untouched for the past year and now randomly it says web server down. I cannot figure out whats going on here but it definitely has to do with cloudflare because when i change the nameservers back to siteground it goes back up but i cant leave it like that. everything on my cloudflare dashboard says everything is working fine but clearly not. support doesnt respond. please help
What is your ticket number?
Site loads fine for me, perhaps clear cache & cookies and try again? Or, a mobile device and/or incognito mode or different browser?
521 troubleshooting ideas here
the nameservers arent cloudflares right now. ill change it now and you can take a look
Thank you, that change may take a bit to propagate. Under
Advanced Actions in the lower right of the overview page, you can always
Pause Cloudflare on this zone to bypass cloudflare for testing. It’s a tad less disruptive than moving nameservers and is instant on/off.
I’d look in the origin logs to see if you can find the 521 error.
thanks, thats good to know. its changed and it seems like it propagated quickly so there you go. can you tell me where exactly i could find the log? i only see the analytics
Appears to be in process
Check with your hosting provider, I cannot hit the origin on port 80 nor port 443 so I suspect there is an intermittent issue. You should ask them about item 1 and 4 in this CommunityTip
this is what i see on the error log on my siteground hosting:
2023-07-31 21:14:33 UTC [nginx][error] 75259#0: *10523951 openat() "/home/u1375-e9axccp4bzoe/www/shoptrakk.com/public_html/.well-known/traffic-advice" failed (2: No such file or directory), client: 188.8.131.52, server: shoptrakk.com, request: "GET /.well-known/traffic-advice HTTP/1.1", host: "shoptrakk.com"
Please go through these 4 suggestions:
- Check your origin web server. The origin web server might not be running; in that case you should: a) Ensure your web server is running normally and b) Review the server’s error logs to see what is causing the error. If you’re unable to perform these tasks, contact your hosting provider.
- If you have just moved to Cloudflare and you are seeing a 521 over HTTPS, it is possible that your origin server has not been configured to allow port 443 be accessed by Cloudflare IPs. In this case you should configure your server/firewall to being listening on port 443 and allow us to be able to conect. If this is not possible, you can move to using ‘Flexible’ SSL under the SSL/TLS app on the dashboard.
- Make sure that you’re not blocking Cloudflare IPs in .htaccess, iptables , or your firewall.
- Make sure your hosting provider isn’t rate limiting or blocking IP requests from the Cloudflare IPs and ask them to allowlist the IP addresses IP Ranges
