Migrated from:
iotaledger/iri#376

Component: IOTA Light Wallet
Version: 2.5.4
IRI: 1.4.1.2

As part of a project, I have configured via apache:

ProxyPass           /api    http://iota:14265
ProxyPassReverse    /api    http://iota:14265

And I am trying to use the connection string in the wallet

Custom

https://iota.example.com/api

However the wallet will not accept a path as part of the connection address.

Invalid!

Neither CCurl nor Webgl 2 Curl work.
