Cloud builder 4.2 – 502 bad gateway

Cloud builder 4.2 – 502 bad gateway

Cloud Builder in VCF 4.2 has enhanced password requirements.

Thus if you deploy the appliance with a password which doesn’t match those requirements it’s going to be deployed with an error, making it unusable.

While trying to access the GUI you will get “502 Bad Gateway” which is not so meaningful.

Trying to access SSH will fail as well. However, accessing the direct console gives a clear information about the problem.

Based on that there is nothing left than redeploying the appliance.



As part of my VCDX preparation I’ve read lots of books, blogs and other documents to expand the knowledge and fill the gaps. That was partially one of the most valuable parts of the journey where I learned a lot. Without that I wouldn’t probably even read half of those great books.

I can’t say this is something that every candidate must read, but I decided to share this list as a VCDX BoM as I found it valuable for my VCDX-DCV prep.
At some point I used the list to define priorities and also track the timing but lost count at some point 🙂
The list presented here is in pretty much random order.
