Site broken in Internet Explorer/Edge

strange not seeing in Edge for me logged out or in

Microsoft Edge 38.14393.0.0

 

Or IE

 

wow ... hmmm definitely will investigate ! Though harder if I can't replicate issue in IE11/Edge on my end

IE accounts for 1.9% of forum visitors, Edge = 1.1% and Safari = 0.55%

 

hmm not entirely sure if I pin pointed the problem but it seems ngx_brotli module leaked some brotli content encoding headers for non supported browsers like IE11 and Edge for only some page http requests i.e. fontawesome's min css file. Brotli browser support Can I use... Support tables for HTML5, CSS3, etc

Posted an issue to ngx_brotli repo at possible leak of br encoding to non supported browsers IE/Edge ? · Issue #42 · google/ngx_brotli · GitHub

I disabled ngx_brotli compression to test in nginx.conf include file /usr/local/nginx/conf/brotli_inc.conf turned off ngx_brotli compression

Code (Text):

brotli off;
brotli_static off;
brotli_min_length 1000;
brotli_buffers 32 8k;
brotli_comp_level 5;
brotli_types text/plain text/css text/xml application/javascript application/x-javascript application/xml application/xml+rss application/ecmascript application/json image/svg+xml;

and cleared all the caches.

It could also be because of Sucuri cloudproxy in front of the forums caching and serving the brotli content encoding = br incorrectly ?

 

thanks for the confirmation @Kintaro

 

cheers @Xon for confirmation

 

how does it look ? specific pages of forums or all forum pages ? does it happen logged into forums as well as logged out of forums ?

edit: ah updating to nginx 1.11.7 re-enabled brotli compression in /usr/local/nginx/conf/brotli_inc.conf so disabled it again now

 

yeah might need to clear some caches on my end and your browser end

update to 1.11.7 re-enabled ngx_brotli so had to disable it

 

Thanks for the confirmation

 

hmm i think i might have figured it out, i had sucuri end compression enabled (gzip), that might have double compressed some static files as well as mess with brotli compressed assets that would be served from cache ??? will later re-try brotli compression but with sucuri end compression disabled

 

re-enabled ngx_brotli on the forums here for some static assets seems webpagetest.org reports same issues on IE11 and MS Edge browsers, but my local browsers for these versions not showing error yet.
