Very recently, I've had trouble when using the web proxy on my routerboard 450g running RouterOS 5.26. Gmail, Google Drive, etc, will not fully load. The page stops loading or I get an error from Google saying that the page can't be loaded. This only happens on Chrome. If I use Firefox, all is fine. If I disable using a proxy and go back to Chrome, all is fine. This used to work.

I have also found that if I start Chrome with the --use-spdy=off option, it works with the proxy. So, at some point in the recent past google probably changed something that uses SPDY that tickles something in the RouterOS web proxy code.

I'm running the latest Chrome on Windows 7. Can anyone replicate this? Just use your RouterOS web proxy and try getting into gmail.

Same for me, tried on RB435G, RB2011, CCR and also trial X86, with ROS6.4 and 6.5. On all platforms it's broken. I'm not 100% sure, but it happens only on HTTPS SPDY. HTTP SPDY sites works OK. On Squid it's indeed OK.

same problem too, with 750g

Fixed in upcoming 6.6 release:

*) web proxy - fix SPDY server push handling;

Yes, I'm testing a 6.6 RC as we speak.

Let me ask you, if this is the exact problem: Only recently, I have lots of incoming connections from websites. They aren't hacking attempts, and they get through the SPI (established/related), but they aren't quite right to get to the clients ... and they almost look like hacking or dos attempts in the logs, but they aren't. They are semi-legitimate. Is that what this fix is for?

I don't think so.

Yes! On ROS6.6rc1 x86 it's working Thank you Mikrotik

The Web gui doesn't work for me in 6.6rc1,though. Does it work for you?

No, it returns error 406. But why you need to access webfig through proxy?

best regards to all, I am using ros x86 Web Proxy v 6.7,as a web browser using IE11 v 11.0.2 and I have a problem with the loading of some pages (Google,facebook...) i need to refrest pages 2-3 times to open correctly when option in IE11 SPDY/3 is on, when i disable in IE11 SPDY/3 option Proxy operates normally, If anyone else has such a problem, that solution.
