Title: ERR_HTTP2_PROTOCOL_ERROR Last modified: August 27, 2020 --- # ERR_HTTP2_PROTOCOL_ERROR * Resolved [Gruskel](https://wordpress.org/support/users/elevas33/) * (@elevas33) * [6 years, 1 month ago](https://wordpress.org/support/topic/err_http2_protocol_error/) * Hi there, I don’t know if it’s a coincidence or not but since I updated the plugin this morning I’m getting the error ERR_HTTP2_PROTOCOL_ERROR in my web. The thing is that my web loads perfectly only that in very very rare occasions the web load is stopped and I get that message… it happens 1 out of 30 times but I don’t understand why… and everything since I updated the plugin this morning… I just updated it to version 3.0.8.3 to see if it improves… I’ve attached a picture.. thank you.

At the moment I’ve put back the w3 Total cache and the fast velocity minify plugin… but it’s a pity I loved the Lite Speed. * Thread Starter [Gruskel](https://wordpress.org/support/users/elevas33/) * (@elevas33) * [6 years, 1 month ago](https://wordpress.org/support/topic/err_http2_protocol_error/#post-12747242) * Thanks for your time, I hope you check the plugin and give a solution to all these bugs, a greeting. - This reply was modified 6 years, 1 month ago by [Gruskel](https://wordpress.org/support/users/elevas33/). * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [6 years, 1 month ago](https://wordpress.org/support/topic/err_http2_protocol_error/#post-12747274) * Hi, * Apologizes for the inconvenience. * If you could check: * 1. for that HTTP2 error , if you disable JS Push and CSS push , how does it work? * 2. for broken page , I assume it will fix if you disable load async CSS , then it means the issue is from CCSS , please check this [wiki](https://www.litespeedtech.com/support/wiki/doku.php/litespeed_wiki:cache:lscwp:troubleshooting:ccss_unstyle) for how to check CCSS rule if it’s inserted or generated. * Best regards, * [Jacob Hill](https://wordpress.org/support/users/tekfused/) * (@tekfused) * [6 years, 1 month ago](https://wordpress.org/support/topic/err_http2_protocol_error/#post-12754740) * I encountered the same problem.
