App working great in Dev server, NOT in Prod environment, no errors logged - URGENT

[Gaël Oberson]

 

Hi,

 

I have an app that works perfectly on the dev server. On the client side, just after authenticating (using google accounts), it shows a "loading..." message, and when the UI is loaded and the needed data is fetched, it shows up.

 

Here is my problem : I have deployed my app many times in the last 12 months for testing purposes, and got ervery time good results.

Since the last deployment (after minor UI changes), yersterday, my app is doing the authentiaction, displays the "loading.." thing, and then stops loading! even my browser is not loading anymore!

 

On the logs page I dont get ANY exception or error. There I see the logs for the first requests (e.g. /, CSS file, static files like images, the scripts, and of cours the RPC authentication request. All of these run without any problem, but then the rest is not done ! The app stops !

 

Does anybody have any idea, how I can start to debug ? I don't have any exception or error to start with ! And as my app is fully working on the dev server, I really don't know how to proceed.

 

Thanks a lot for your help !

P.S. naturally, I already tried to completely clear my datastore (HR) and my memcache. no effects. I also completely deactivated my app, created a new one with a fresh new app ID, nothing helps. I also tried many operating systems and browsers, I get everywhere the same not usable result.
