Getting Error 505 - Anyone Know How to Fix This HTTP Version Not Supported Issue? or Error 505 - HTTP

"Help! Error 505 When Loading a Site - What’s the Fix?"

Yo, so I keep hitting this *error 505 - HTTP version not supported* thing when trying to load a site. Super annoying, right?

Anyone else run into this? It’s like the server’s all *"nah, I don’t speak that HTTP version"* and just bails. Tried refreshing, different browsers, even my phone—same error 505.

Is there a quick fix or do I gotta dig into server settings? Not super techy but willing to try stuff.

Thanks in advance!

"Error 505 - HTTP Version Not Supported. How Do I Resolve This?"

Hey folks,

Getting this *error 505* on a site I need to access. Says "HTTP version not supported"—no clue what that means lol.

Tried Chrome, Firefox, even Edge... same deal. Is it on my end or the server’s problem?

If you’ve fixed this before, pls share how! Short on time and this is driving me nuts.

Cheers!

Ugh, error 505 popping up like it owns the place. "HTTP version not supported" — cool, but how do I *make* it supported?

Cleared cache, restarted router... nada. Site works for others tho, so it’s gotta be fixable, right?

Drop your wisdom below! (Or just sympathy, that works too.)

Thanks!

Hey! Had the same error 505 issue last week. Turns out it was the server rejecting HTTP/1.1 requests.

Try forcing HTTP/2 in your browser—type *chrome://flags* in Chrome, search for "HTTP/2," and enable it.

If that doesn’t work, the site’s server might just be misconfigured. You could use a tool like Postman to check if it’s really a server-side prob.

Good luck!

error 505 is usually a server-side thing, so not much you can do on your end.

But hey, worth trying a VPN or proxy—sometimes the server blocks certain IPs or regions. I used ProtonVPN and it worked for me once.

Also, check if the site works on DownForEveryoneOrJustMe.com. If it’s just you, blame your ISP lol.

Ugh, error 505 is the worst. Had this happen when my work’s firewall was messing with HTTP versions.

If you’re on a network (like office/school Wi-Fi), try switching to mobile data or a diff network.

Otherwise, the site admin needs to fix their server config. Maybe tweet at them? Annoying but effective.

Yo, error 505 gang!

Quick fix: Open dev tools (F12), go to the Network tab, and reload the page. Look for the HTTP version in the headers. If it’s 1.1, the server might hate it.

No luck? Try curl in terminal: *curl -v --http2 [URL]*. If it fails, def a server issue.

error 505 usually means the server’s picky about HTTP versions.

Try this: Install the "HTTP/2 and SPDY Indicator" Chrome extension. It’ll show if the site *supports* HTTP/2. If not, the server’s outdated.

Or, use Wayback Machine to see if an older version loads. Desperate times, right?

UPDATE: Yo, thanks for all the tips! Tried the HTTP/2 flag in Chrome and it *kinda* worked—site loaded but super slow.

Weirdly, my phone on 5G worked fine. Maybe my ISP’s being weird? Gonna try a VPN later.

Appreciate the help, y’all! If anyone’s got more ideas, hmu.

Not a techie either, but error 505 drove me nuts till I found this:

In Firefox, type *about:config*, search for *network.http.spdy.enabled.http2* and set it to *true*.

If it still fails, the server’s just broken. Bookmark this site for later: https://httpstatus.io/—helps debug HTTP errors.

error 505 is like the server ghosting you lol.

Try disabling browser extensions—some mess with HTTP headers. Also, check if your browser’s outdated.

If all else fails, contact the site’s support. They might not even know it’s broken!
