I've inherited a setup using app-engine flex and (afaik) this means our api gateway is managed. Last week were getting a 502 from NGINX. We ultimately solved it by redeploying but I want to understand what happened.
Where might I be able to see logs for this? Do I have any control over the NGINX setup? Could I have just restarted the api gateway instead?
Thanks
It looks like something that should raise with tech support. Remember to provide your Project Number and not your Project Id as it is PII.

We just started having lots of 502 errors out of the blue, without deploying anything new. Somehow 99% of all requests to the endpoints don't get through to appengine (as seen in the appengine log). The service status of google app engine and endpoints seems to be green.
We tried deploying a new endpoints api description and a new appengine version using it, also stopping respective versions.
We can also no longer look at the api explorer.
web requests via the gapi js library return "Error 502 (Server Error)!!1" when trying to initialize and load the "_ah/api/static/proxy.html" page
What could be the problem here? Is there a way to "restart" endpoints?
OK, its just magically started working again after around 50min of downtime. I guess it would still be interesting to know if there is anything we could do in cases like this.
App engine is in use.
If you click on the version of the service, an error 502 occurs.(appspot.com)
However, there is no problem access to the domain connected to the service.
I want to know why.
There seems to be and issue with the GAE traffic in Asia, which is probably related to your error. The Google engineering team is investigating it with high priority.
For server issues that doesn't involve a potential coding/configuration error on your end, please use our issue tracker. You can report all potential bugs / feature requests there, thanks.
When will SSL support for custom domain be available within the developer console, instead of having to go over to Google Apps? I read somewhere it says Q3 of 2015. But seems like people have some ways of getting that to work already. Is it a private beta feature?
Building some apps for a client and they can't get their Google Apps account to work and we already have the custom sub-domain mapped to the GAE, and just need the last piece. Help!
This is the tracking issue, indeed Q3 seems to be more likely: https://code.google.com/p/googleappengine/issues/detail?id=10794
FWIW, I detailed a bit my solution to get things working via Google Apps in this Q&A: AppEngine subdomains to modules without wildcard mapping, maybe it can help with your customer's problems in the meantime.
I try to make a SP hosted on Google app engine, with a third party IdP, and I'm facing multiple problems.
I'm using Spring SAML extension for java. I was able to run the stand alone (not in GAE) demo app, from the official guide http://docs.spring.io/spring-security-saml/docs/1.0.x/reference/html/chapter-quick-start.html using as IdP idp.ssocircle.com.
Now my problem comes whey I tried to integrate this code in my GAE project. When running with GAE I can get to the phase where I'm redirected to do the login on ssocircle.com and from there when I should be redirected back to my page I'm getting this error: "Error 401 Authentication Failed: Error decoding incoming SAML message", and on local GAE server logs I can see this message
"[INFO] Dec 17, 2014 5:21:23 PM org.apache.commons.httpclient.HttpMethodDirector executeWithRetry [INFO] INFO: I/O exception (java.net.SocketException) caught when processing request: Permission denied: Not allowed to issue a socket bind: permission denied."
I was wondering if this is a limitation from GAE regarding sockets: 1) Sockets are available only for paid apps (I don't have a paid app, but could consider this options) 2) You cannot create a listen socket; you can only create outbound sockets. 3) You cannot bind to specific IP addresses or ports. (for me this one sounds like it is my problem).
And whey I tried to deploy on GAE, the app remained in a start-up loop because of other errors regarding "nested exception is java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "modifyThreadGroup")", that sounds like another GAE limitation to me.
At some point I was ready to gave up, because I was thinking that SAML Spring extension can't work with GAE, because of limitations present on GAE. But I see you have the same project running as a demo on GAE (or at least I think it is running on GAE because of the appspot part in domain name). https://saml-federation.appspot.com/saml/discovery?returnIDParam=idp&entityID=saml-federation.appspot.com
I would appreciate if you can give me some hints regarding my problems, and best would be if you could help me with the source code of this demo project (could not find it anywhere), and all configuration that is needed for GAE.
I've created a new repository https://github.com/vschafer/spring-security-saml-gae which includes instructions for deployment of Spring SAML applications on Google Application Engine. It also includes classes helping to avoid issues you're facing (sockets and threads).
In order to use it:
include the jar created from the repo in your project
use the provided org.springframework...StaticFilesystemMetadataProvider for loading of your metadata
in case you are using HTTP-Artifact binding replace bean org.springframework...ArtifactResolutionProfileImpl with org.springframework...google.ArtifactResolutionProfileGAE
Please comment if you spot some mistakes in the documentation or code.
I am one of 2 developers on a silverlight project that is hosted online. The problem is that i seem to randomly have problems with our webservices not working (This never happens to my colleague).
Using firebug, i had a look at any problems that it was reporting and i found this:
GET clientaccesspolicy.xml 404 not found
GET crossdomain.xml 404 not found
Any ideas why only i have a problem with like this?
We have both cleared out our cache and recycled the application pool of the webserver... no joy.
Thanks,
Kohan
So the webserver intermittently returns 404 errors on the policy file? What version IIS?
If your colleague never gets the error, compare the request headers between his system and yours to be sure there isn't something weird going on.
If the policy file is hosted by a provider and you're getting intermittent 404 errors you should put in a ticket with the provider.
This happens when the client attempts to connect to a domain on which it is not hosted. The policy files are used to grant access to that server from the SL client.
Are you both running the client from the same location? Double check your proxy settings and hosts file too.
Found out the problem came when accessing the site without typing "www."
I should have known to check that first. :(
