I have a weird problem, for which I researched a lot, but no luck!
I have created an External Switch in Hyper-V, which in turn creates a network bridge on my Wifi adapter. I'm facing this issue that, for a specific Website, when I try to go to the login page, I see the ERR_SSL_BAD_RECORD_MAC_ALERT
error in Chrome.
I have attached a screenshot: the Website is also there, in case it helps:
It's worth noting that if I right-click on my Wifi adapter and select Remove from Bridge
, I don't get this error (of course after a required restart so that my connection works)
I have also included a screenshot of my network adapters and the Properties
page of the network bridge; maybe that would help:
Any help is really appreciated.
Thank you

@Ramhound - I have the exact same problem for a few weeks now. I don't think this is the same error at all. Note it only happens when using the "network bridge" pseudo adapter. Unless you know how to change how this thing work? Can we configure some MTU for this bridge? It does that on all browsers. But, for information, if I use Firefox and set the its
security.tls.version.max
config option to 1 (default is 4), it works. Weird. – Simon Mourier – 2018-12-01T10:12:06.270I actually found something that sems works for me... Go to the vEthernet that correspond to your bridge, edit its properties and configure the "Hyper-V Virtual Ethernet Adapter". Change the "Large Send Offload Version 2" to Disabled for IPV4 and IPV6.

– Simon Mourier – 2018-12-01T11:16:03.673@SimonMourier your workaround worked for me too :) . The question is: is doing that dangerous and causes my connection to be less secure? I'm asking because I have no idea what that
Large Send Offload Version 2
does – Farzad – 2018-12-02T15:56:13.760@Farzad - it has nothing to do with security. It's more a performance feature, but actually, if you google on this, you'll see some people recommend to disable it on hyper-v because it can cause performance issue. Go figure. – Simon Mourier – 2018-12-02T17:19:50.350
