Wordpress LScache Plugin: ERR_SPDY_PROTOCOL_ERROR
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi. After latest update my website shows constant error This site cant be reached The web page at mywebsite.address might be temporarily down or it may have moved permanently to a new web address. ERR_SPDY_PROTOCOL_ERROR I found workaround. Disable lite speed cache. Tried to disable most setting one by one but my website is available only with disabled LSC P.S. I was thinking it is somehow connected with cloudflare, but disabling cloudflare doesnt help This topic was modified 3 years, 3 months ago by ArtakEVN.

Site is available when Im logged in. No problem with admin either. After purging cache it works on first load. After that ? same issue. Disabling Cache Login Page , Cache favicon.ico , Cache PHP Resources and Cache Mobile also helps. Looks like it is because of something in .htaccess file written by LSC Also, uninstalled plugin, deleted all cache folders, started again with new instalation of LSC ? same result. Other WordPress website works fine with same settings. The only big difference is elementor on problematic WordPress. 3rd wordpress->woocommerce with no elementor have the same problem. Firefox shows another error. Maybe this will be helpful Secure Connection Failed An error occurred during a connection to ? The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem. Hi, I see you are using CloudFlare. So could you please verify: 1. If you activate LSCWP and disable or bypass CF, does it work fine ? 2. And you mentioned that Disabling Cache Login Page , Cache favicon.ico , Cache PHP Resources and Cache Mobile , if you only disable only one or 2 or few , not all 4 of them , it wont work ? Best regards, If you activate LSCWP and disable or bypass CF, does it work fine ? It was hard to test, honestly. Cleaning cache every time, disabling antivirus, flush dns after each test. But finally can say, YES, it works when CF is in Development Mode an Paused (not sure if I need them both, but just in case). Hi, If you set up a new WP site on sub-directory in same domain as your main site, does this issue also happens on this newly created WP? Best regards, Yes. Actually I have onother WP in sub-directory and it has the same issue as Parent installation Hi, Please create a ticket here, we will investigate it further. Best regards, For anyone following this topic, the issue is still being looked into.
