Bridgeways VMWARE ESX/VC subscriptions fails

28 Nov



You want to add a new VC server to the Bridgeways ESX monitoring using the “Bridgeways VMware Management Administrator” tool. But the connection always fails. You checked everything user / pwd / IP , all okay


1) First check if the network routing is okay. Open IE and type https://<ip>/sdk

You should get a SSL warning. If not you will have to check networking.

2) If you checked networking and you can connect to the VC but still get no SSL warning you have a SSL RSA problem.


On Windows 2008 and above the RSA minimum bits are 1024. All other certificate length will be blocked. See .

So check you certificate properties and look for the RCA bits length. I think it will be 512Bits.

To solve this:

Open under admin a CDM console and execute this.

Certutil -setreg chain\minRSAPubKeyBitLength 512

Now retry your add action.


Happy Scomming

    Only keys smaller than 1024 bits are blocked as per your linked article (and not smaller then 2048 bits). Keys with the size of 1024 bits are still accepted by the new security requirements.

      You are completely correct. I will change it in the post. Typos happen 🙂 Thanks for reporting Michel
