iOS: dhcp-option PROXY_AUTO_CONFIG_URL not working

[ryanpc]

dhcp-option PROXY_AUTO_CONFIG_URL no longer works

The setting in my ovpn config file stopped working with v1.2.5

It is still broken in v1.2.6

I'm using a local .js proxy URL eg: ​ http://aa.bb/AbA1BB.js (used for Weblock ad blocking)

iOS 11.2.2
iPhone X

Info about the Weblock adblocking .js proxy here:

Can you please share your connection log?

Thanks

Issue identified. Will be fixed in the next release

Here's my log file from a successful connection today (PROXY_AUTO_CONFIG_URL setting was still not respected):

Thanks!
However, the fix for this bug is already undergoing beta testing

[Antonio Quartulli]

v1.2.7 is being rolled out to the various AppStore? as we speak. Please test it once you have a chance to upgrade and update this ticket accordingly, if possible. Thanks!

[ryanpc]

Updated, tested - it works again! Thank you very much!

[Antonio Quartulli]

Cool! closing. Thanks for the feedback!
