I've been getting this error: Cannot Authenticate: This may be due to that your Internet connection is down or either firewall or a proxy are blocking...
REASON: OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to account

//On a side interesting note, doesn't matter what password I'm typing in, it still give that error so I'm guessing something is not connecting correctly?

I've tried everything I could think of;
- Switch firewall off
- Internet is definitely ON
- I install the latest R21, reinstalled twice.
- All Cuda drivers up to date
- Tried 2019.1.1-R3 and tried 2018.1.3-R5
-Took my machine to another office to see if the internet is "different" - no luck

Running Windows 10 Pro, Cinema R21. , Nvidia 2080Ti Driver 431.86

I really need help, please. AS usual in the middle of deadlines and need this machine to work desperatly

THANKS for any help!

Hi,
please, try switching to the DNS service provided by Cloudflare:
https://1.1.1.1/dns/

I dont know how switching DNS is going to solve this, all our other machines are running on the same network with no issue. Anyone else have ideas?

Do you have a Proxy server?

OK, I've figured it out, thanks for the advice @bepeg4d

All I did was:


1. Internet Options
2. Click on Connections Tab
3. LAN Settings
4. Automatically detect settings (mine was on "use proxy server for LAN...')

Also, I used wifi instead of the network but I don't think that would have an issue?

Hi,

From the error code shown in your screenshot and your later note about removing a configured proxy server,
the likely cause of your issue would have been a proxy that was attempting (and failing) to MitM the SSL connection.
