ExceptionOnConnect

Claytonious

Using Unity3D (but with the "plain" SDK, not PUN), with Photon Cloud, against app-us.exitgamescloud.com:5055, after calling my LoadBalancingClient's ConnectClient() method, then:

* On the desktop, everything works - connect fine
* When deployed to an IPad, the same code (same app id, same URL, same code, etc.) ends up with a status of ExceptionOnConnect and fails to connect. The overridden OnStatusChanged on our is called and passed a value of StatusCode.ExceptionOnConnect.

What does ExceptionOnConnect mean? Why am I getting this only on the iPad and not on a desktop build of the same codebase? The iPad *definitely* has a good WIFI connection and is having no trouble reaching other sites and services. It can even browse to us.exitgamescloud.com, which presents us with a IIS screenshot.

Any ideas why we cannot connect from iPad but can from a desktop build?

Thanks!

The error means that the game couldn't connect to our server for some reason. So connection was never established at all.
I would like to see the log from the client. You can grab it from the device easily with the "Organizer" in XCode. Maybe it has some important hints what goes wrong.

Which Photon Unity SDK version are you running? The latest from our download page? Which Unity version?
In any case: I think we will find a solution. It worked before and there's no reason it shouldn't.

The console output from the device is uninteresting - mostly output from our app, not Photon, but I've included it below anyway for your reference.

This is Unity 4.3 Release Candidate 1, but same problem with Unity 4.2.x. Yes, this is the latest Photon SDK download, but as I mentioned here in another thread, it's possible we're not using the right DLL.

This seems like such a basic failure - guess I will try it again in a minimalist project to see if it reproduces that way.

Found the issue - you have to use a stripping level of "Strip Assemblies" or higher when you build to iOS with Photon. (Photon is trying to use some of the overloads of Socket's constructor that require ConfigurationHost, and most of that was getting stripped out with our more aggressive "strip bytecode" setting.)

This needs to be front-and-center in bold text at the top of the docs and readme.

Thanks!

> Photon is trying to use some of the overloads of Socket's constructor that require ConfigurationHost, and most of that was getting stripped out with our more aggressive "strip bytecode" setting.

I simply wasn't aware that "Strip Assemblies" will break the build. A while ago, I got told to use "Strip Bytecode" and didn't touch this setting again.
I will put this hint into the readme and into the iOS section of the readme.


Is the "Already authed" related to Photon or some other authorization?

Claytonious

The "Already authed" was something else - not related to Photon at all.

And here's an important update on this issue: it was not the "Strip Assemblies" setting, after all. It was the "Dot Net 2.0 Subset" option that fixed it. So, here is the actual issue:

1. If you build to iOS from Unity with "Dot Net 2.0" API setting, then you will get this error (ExceptionOnConnect due to Socket constructor).
2. You must change it to "Dot Net 2.0 Subset" in order to fix the problem.

(I had inadvertantly changed both that and also the stripping level at the same time, which is why I mistakenly thought the stripping level was the fix).

This is going to a serious roadblock for anyone who needs the full 2.0 API, though. We are able to use the subset for now, but there will be some projects for whom this is not a workable solution. I highly recommend that you guys use a different overload of the Socket constructor, or possibly do something else, to fix this issue for Unity users.

Thanks!

Tobias

As it's not a compile issue, I think we (you) should send this as bug report to Unity. Obviously the Subset and Full API are compatible but behave differently. That can't be the idea of the Subset, or could it?

Anyways: As this is an issue, we can take a quick look at the full api and maybe we can work around the exception, too.
Thanks for the analysis.
