I just upgrade my server to Apache along with Ngix to make my website faster.
Every things works fine but When I enable HTTP/2,I can not access to website that use Newsmag WP Theme from my iPhone or iPad. Ngnix returned error to “502 Bad gateway”. It can access from Desktop browser also android browser. I tried to access another website in same server that use other WP theme with iPad. It’s work fine.
What is the reason of this problem? Any one can give me some solution or advice to solve this problem.
Ideally, site should be https php5.6 or 7, and if using nginx make sure you dont have apache directives in htaccess. Http/2 is server managed and shoukd have nothing to do with theme. Check server error log for what is going on..only way you can sort that out.
Oh… just reread that. On ipad you may have to clear cache completely… i ran into this with custom fonts loaded locally on server… im on ipad right now ???
yes, my site use HTTPS (SSL) along with PHP 7.1. Thank you for your advice . I will check server error log.
One thing to notice is when I enable HTTP/2 website using NewsMag will return to 502 Bad gateway but other website using other theme it works fine.
Our NewsMag website runs fine on HTTP/2 https://www.1uhost.com
Check error log /etc/apache2/logs/error_log OR /usr/local/apache/logs/
Often the 502 happens due to too many processes running (kill script). You can try limiting queries, turn off stuff like XMLRPC, images in search box, related stories with images (more from author), ajax show more, infinite pages scripts, mega menus with posts; increase execution time for php, memory allocated to site, memory allocated to WP (e.g,. 256M vs default 40M in wp-config.php – ) etc.
Thank you Chris and iisnet for suggestion.

None of the above errors are caused by TagDiv so you need to fix your server.
Check for syntax errors in nginx.conf. As root run:
service nginx configtest
Check nginx is listening on the configured ports;
lsof -P -n -i :80 -i :443 | grep LISTEN
These errors:
“Got error ‘Primary script unknown\n’, referer: http://ping.rootblog.com/rpc.php”
just mean a non-existent php script is being requested.
Also, note most http/2 installs *do* require https, and site fully configured and optimized for that (meaning all elements, content, scripts, external files, etc.) served via https.
Technically speaking, HTTP/2 does not require https to work, its just that all of the ‘popular’ browsers decided that they would only recognise HTTP/2 if the connection was over TLS/SSL, in other words a url beginning https://
Yes, I am well aware having managed our own servers since 1996. However *most* web hosts are requiring https for http/2 as a standard with the ‘https everywhere’ movement.
Much like Google will be warning site visitors about “site not safe” for any website with an insecure form in October. Everybody *should* be moving to https. Period. We moved all our sites to https in 2004, not just the ecom systems on sites.
Obviously anybody who can read up on the topic knows that.
My point was that somebody trying to switch on http/2 on their server as a hosting client, where the server policy is to enforce https for http/2 will have errors and perhaps generate ‘port’ errors since there will be mis-match on secure/insecure ports, much like with mod_pagespeed couple years back (2013? wow time flies!) with mixed content.
server certificate does NOT include an ID which matches the server name
For example on a Plesk/ONYX server, “Make sure that SSL support is enabled for the web site in the Hosting Settings section of the domain. HTTP/2 is supported for SSL sites only, so non-SSL sites will continue to work under HTTP /1.x. That is a restriction of nginx web server and web browsers.”
My comment was intended for the OP who might not understand what he/she is actually doing with this process.
Cheers.
HTTP/2 is supported for SSL sites only because of web browsers policy, not because of any web server configuration or policy. If HTTP/2 is enabled its enabled globaly. Your comment is good but like mine its starting to get off topic 🙂 I’m sure we can both agree this thread/problem has nothing to do with TagDiv software so I will sign off here and go grab a beer!
Sure. Whatever. For servers running NGINX and Plesk, http/2 will not work. This was the point for the original poster (OP). So, no https setup or proper cert would generate errors and http/2 would not work at server level.
So, if browsers require it and certain servers require it, that = ‘required’ beyond the technical issue of the format which originally required it, then didn’t, but now technically does to work for most instances. So, moot point beyond historical discussion.
So, my point is still valid. Yours added nothing to the actual issue, but thanks for the input and hope you’re enjoying the theme 🙂
(I’ve been lurking here since TD launched, but don’t work here … and I’m a bit of a dinosaur on this stuff – having been building sites since 1995, and WordPress since 2004.)
I’m out!
HTTP/2 works on Plesk versions >12.5, and on NGINX versions >1.9.5
Bye.
Yes — already noted in my posts. http/2 on Plesk requires https.
Not sure point of your comment. But again, thanks for chiming in !
Feel free to reply to get last word in, I’m no longer following thread.
