I made some changes to my Wordpress https://mikeschaffnerphotography.com set up (hosted on Bluehost with Cloudflare as CDN). It was working fine after the changes and then a little while after (1 - 2 hours later) I could no longer visit the site or login to my Wordpress dashboard. The error I get is “This site can’t be reachedCheck if there is a typo in mikeschaffnerphotography.com.
If spelling is correct, try running Windows Network Diagnostics.
Strangely I cannot access my site while on my network (Xfinity/Comcast) either on computer or mobile. However, when turning wifi on mobile off I can reach the site but not my wordpress loging https://mikeschaffnerphotography.com/wp-admin/ Perhaps this is because I’m not really seeing the “live” site but the cached site via CF’s “Always Online” option?
The changes I made are below starting with the one that seems most likely to be an issue.
- To improve security in Cloudflare I enabled DNSSEC. It gave me a number of setting that needed to be made on the Bluehost side before it would work. Looking at Bluehost I could not find anywhere to see or change settings for DNSSEC. I chatted with Bluehost support and they informed me that DNSSEC was already enabled on BH and gave me a link to a page that showed it enabled. The conclusion was that I would therefore not need to enable it on the CF side. The confirmed I could just cancel the request on CF which I did. No setting were explicitly changed. After cancelling the request all functioned normally until a while later when it stopped.
- Over the past few days I was testing using HSTS. Yesterday I increased the MAX-AGE from 2 months to 1 year. Again, all functioned normally until a while later when it stopped. I don’t see how HSTS would cause this and in particular a MAX-AGE change shouldn’t.
- In trying to establish a Content Security Policy I established one in “report only” mode. Again, all functioned normally until a while later when it stopped. I have since commented this out in htaccess so it is no longer active. However, this had no effect on being able to access my site not that I really expected it would.
Any suggestions on what could be causing this?
Thanks for your help.
