Clientless RDP access - websocket error

Edtrick Lam

Recently I connected to Sophos portal and using clientless RDP access to my office computer, I got websocket error in chrome browser.

I tried IE , Edge, opera browser is also same error.

except Firefox 78.0.2, which is all right to use clientless RDP to my office computer. 

As I get through a sophos community, I can't find any solution. 

In chrome, I tried to inspect , it shows following error. (Even I added sophos applicance cert in my remote computer, I still got a same problems)

WebSocket connection to 'wss://x.x.x.x.:xxxx/screenmgr' failed: Error in connection establishment: net::ERR_CERT_AUTHORITY_INVALID

Uncaught TypeError: Cannot read property 'options' of null

Please advise any other solution to fix it.

Thanks.

    Hi  

    Any luck with deleting and creating clientless access again or with service restart via below command?

    #service clientless_access:restart -ds nosync

    I tried deleting and creating clientless access, restart services, and reboot XG135.

    Still same websocket error in Chrome, IE, Opera

    But work in Firefox 78.0.2

    My XG135 Firmware version: XG135 (SFOS 17.5.12 MR-12)

    I am thinking to upgrade firmware, but I see a lot of post firmware 17.5.13 MR-13  and 18.0.1 MR-1 is not stable. Also 18.0 version is total different pic...

    It make me worry for those upgrade.

    Any other solution to solve this problem??

    Thanks

    Noted. thanks. 

    I checked the log of clientless access log in firewall, it shows following:-

    Aug 13 10:29:25 [4020]: INFO: Client 0: authenticated: user='edtrick'

    Aug 13 10:30:04 [4020]: INFO: Client 0: connector stopped: 8

    Also for my datacentre firewall XG125, I also tested clientless , also got websocket error. 

    still checking and figure out client side or firewall problems..
