Not sure if i am adressing this issue to the right section, but since yesterday i have been getting this message when i try to enter e621 by using Opera browser, it says that it cannot establish a secure connection because this site is not using a supported protocol. What does this mean?

It might be because of the browser not agreeing with the http protocol from CloudFlare.

Or your problem might have a relation to this .

If you're using Opera 12, try disabling OCSP:

1. Type opera:config into your address bar and hit Enter
2. Type ocsp into the search bar at the top
3. Uncheck the 'OCSP Validate Certificates' option that appears

You may or may not have to restart Opera for the setting to take effect.

I haven't been able to reproduce this on Opera 12 or Opera 32 for OS X, but the issues you are seeing may be OS-specific. Since most browsers* use the OS to verify certificates, sites with newer types of encryption will fail to load if they don't fall back to a less secure (read older) encryption type.

Operating systems affected by this include:

• Windows XP or older
• OS X 10.5 or older
• Android 3.x or older
• iOS 3 or older (rare)

If you are using one of these OS's, I would recommend you either upgrade your OS to a newer version, or use Firefox*.

*Firefox is one exception to this. It uses its own certificate verifier instead of the OS's, so sites affected by this should load fine in Firefox regardless of OS.

Comment saved for posterity

dtech-x (Aug 23):

Opera is censoring content, It's a no-brainer. All the other sites work as usual, & only specific sites are getting this error message. it's no error at all if you ask me.

Opera is a fork of Google Chrome, Chrome is owned by google, & google is the biggest privacy bandit of them all. They are censoring access to sites.

If this is not the case, then it must be due to something similar. NOT DNS, or SSL protocol crap that is always claimed. The sites are clearly there, but the browsers refuse to continue on into them, & simply displays that page about protocol nonsense.

Sooner or later, all those who didn't pay their taxes, or whatever else, wont be able to access anything on the web by this exact methodology.

Whatever it is... Russia, & China saw it coming months ago, & has started building the infrastructure for a new 100% free, & public Internet, with brand new Top Level Domains to replace com, net, org, & whatever else. I'm removing Opera now, & chrome as well.

This world is run by crooks, & those who would sell their mother for a quick buck. Anything you sign, enter, or save in these browsers goes up to the highest bidder... especially deep pocketed corrupt government agencies. If you think otherwise, then your an idiot.... plain, & simple. The databases to store the billions of bits of data for each user is outrageously expensive to maintain, yet they offer it for free?

It has begun.

I approve the name "Blackbird71"

Which Opera version are you using? I use version 12 (both PC and Android) and I don't have that issue. But as tony said, it's worth trying with OCSP Validation disabled (this should be available on Opera 15+ too but you'd have to check the Google Chrome help docs)

Also, telling your OS version can help us help you.

Thanks everyone for replying and helping out. Yes, I forgot to mention i use Windows XP as my OS and my Browser is Opera 32 and FireFox 41. So I guess i will follow your suggestions until i can upgrade.

Also, I forgot another detail. When I try to open this site through Firefox, my antivirus Avast 10.4 stops the access due to ssl277549.cloudflaressl.com is not valid certificate, does this mean that the antivirus also uses the OS to verify certificate? if yes, then they all should be like Firefox.

Edit: Meaning that i have to turn off my antivirus shields to gain access to this site, otherwise it doesn't load.

I did what you said and it put -Nothing found for "OCSP"-

Edit: Never mind, i missed the part this was for Opera 12. And i use Opera 32

[o]Opera 32[/o]

They're up to 32 already? Jeez, they skip a shit ton of numbers. Do they have tab stacking back in yet?

Not that I know, but they skipped from 12 to 15, 12.17 being the latest of the 12 series. For the WebKit version (O15+) I assume they follow Chromium's version numbering, but

*checks*

Nope, no tab stacking yet

From what I understand, Avast HTTPS scanning works more/less by using a novel method to route the encrypted traffic through its scanner (it uses its own certificates to encrypt the content, as a sort of man-in-the-middle hack). Unfortunately, a lot of sites don't like it when you do this and many users have found that disabling the feature fixes connection issues on those sites.

Fortunately you don't have to disable the antivirus entirely as you can disable just the HTTPS scanning part (it's in the Main Settings, uncheck "Enable HTTPS scanning"). Just note that leaving it disabled may increase your risk of malware on other sites.

Thanks for the advice. I don't know what actually fixed the problem for me, but i am able to open the site again through Opera 32. Maybe i just had to wait for the certificate being updated. Sadly, Avast is still blocking the access when i use FireFox 41, maybe it will be solved when Avast or FF update again :)

Fucking lame. Guess I stay with Firefox.
