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.
