@andrewwhitehead - doesn't seem to work with the full URL. The connection process definitely starts, but I don't get a prompt in the Alice window - it just seems to hang as below:

Startup duration: 3.52s
Admin url is at: http://172.17.0.1:8031
Endpoint url is at: http://172.17.0.1:8030

Same behaviour if I just paste in the base64 encoded text:

On the agentbook side, it shows that it received the connection request, sent the connection response and then...nothing.

Leaving Alice running, I eventually get this error:

@swcurran Is your Alice agent routable?

[swcurran]

@andrewwhitehead - don't know - I'm just using the "run_demo alice" on the ACA-Py side. I just know that what worked last week with Agentbook does not work now. Last week, I had to decode the URL to grab the JSON invite, but once I did that, everything worked. Now it hangs as noted above.

[swcurran]

FYI - same behaviour as last week (using the base64url decoded JSON data) fails as well - no connection established. This is the data I used:

{"recipientKeys": ["3KwBC89e7WNhPMJDe3WvyTfrPgJZJt739pTm5hD2a8Tw"], "routingKeys": [], "serviceEndpoint": "https://agentbook.vonx.io:10000", "label": "AgentBook", "@id": "51779334-5df9-4307-b56b-7b61d98891d6", "@type": "did:sov:BzCbsNYhMrjHiqZDTUASHg;spec/connections/1.0/invitation"}

[swcurran]

Previous notes were based on tests with a local agent, which (of course) is not going to work. Once I moved the test to Play-With-VON, all worked well.

Sorry about that.
