Explorer 2: "MultiChain is not running: unknown url type:" exception

+2 votes


I am having an issue with multichain explorer 2. The chain is running and the multichaincli too (tested those). The configuration files were edited as explained in github but I am runinng into the issue that the status of the chain (named chain1) is displaying "no connection" and the exception "MultiChain is not running: unknown url type:" appears when I click chain1. (both the chain and the explorer are running in the same machine)

Edit1: We have the exception:

Exception occurred during processing of request from ('', 44180)
Traceback (most recent call last):

The exception text is: HTTP Error 401: Unauthorized

Assuming that the node is running on a different server to the Explorer, you need to use a setting in the node's configuration to allow access from the other server's IP address. Search this forum for rpcallowip and you'll find lots of answers.
