SSL Bad Header version error

Hi Guru,

We need your help. I have the same problem encounter SSL BAD Header version.

Thanks,

From what wyse support told us, VMware 6.2.1 is not compatible with the Dell/Wyse D10P thin clients firmware. We had to downgrade to VMware 6.2 until Dell/Wyse releases an update to the firmware that is compatible with VMware 6.2.1. My guess is it has to do with SSL/TLS versions not being compatible.

Hi Jef0226,

Question, is it working After you downgrade the version of your view from 6.2.1 to 6.2?

Thanks,

Yes we downgraded both Horizon View server and View agent to 6.2.0

Yes our thin clients started working after we downgraded. Still waiting for the new firmware from Dell/Wyse before we can upgrade to 6.2.1.

Hi,

Thanks for your reply, just to clarify, do we need to downgrade the version of Horizon View server and View agent? our current version of Horizon View is 6.2.1 and also the view agent.

Appreciated your quick response...

Thanks,

Jhero

If anyone else is having this problem, there is a proper solution in form of firmware upgrade. To sum up the steps I've done (wasn't easy)

• Create an account at https://support.wyse.com  and register your device.
• You need to have a valid maintenance contract do be able to download the firmware versions.
• I bougth it here, excellent service and pretty fast (we had the code in less than 24h) http://www.wysechoice.co.uk/epages/BT4858.sf/en_GB/?ObjectPath=/Shops/BT4858/Products/%221%20Year%20Maintenance%20Thin%20OS%2C%20730958-02%22
• Download the WTOSD10DP_8.2_017_HotFix.zip file
• Basically upload the uncompressed file to the wnos folder in an anyimous ftp server, if you point the zeroclient there it will just download the files and update itself.
• For any doubts, open a ticket, they were quite helpful

Good luck
