Google Cloud Server suddenly stopped working. Yesterday I got the error , " Error establishing database connection".
Today it is "Request Timeout
Server timeout waiting for the HTTP request from the client"
Any suggestions to get over this issue??
This could happen based on the configuration you have on your app.yaml. If the instances are overloaded you might encounter a 408 when trying to communicate with the server, in that case changing the scaling configuration on your yaml file might fix the issue.
This document can help you with configuration of your yaml file, information with auto and manual scaling, healthcheck, readiness check etc.
And this article would give you general information on how scaling work on App Engine and best practices.
Also, if you’re using WordPress, this is a common issue with WordPress

I am experiencing a web socket connection error when I have not used web sockets anywhere in my codebase.
Below is an image of my problem:
Breakdown
I have two applications hosted on Heroku, one for the frontend client and one for the backend server. The client is developed with React and the server is developed in Python / Flask. The server is not showing any of these error messages.
This error will periodically show up and I'm not too sure what the root cause is as there's no real way to trace back to the file shown in the image.
All the posts I've found relating to this error has code that uses web sockets in their codebase which is much different from my situation.
I was wondering if anyone else experienced this and found a work-around.
The problem was that I was using the development server in the production environment. This shows how to set up a production environment for Heroku.
Cheers.
Recently one of our sites got suspended by Google Ads due to "Destination Not Working". When I talked with Google Support they told me that my site is not accessible from all location globally. Then I tried to investigate, the site is hosted on Google App Engine. And I didn't find any 500 errors. But sometimes some website checking tools like "Uptrends" showed me inconsistent error "Http Protocol Error"/500 error. Then I tried to see closely on Google stackdriver logging and ran several tests on Uptrends and on other tools. But I saw something like this.
And on App Engine logging, I saw something like -
And also sometimes some HTTP request is not hitting my app so my app logging is not working and it's bothering us so much. We are losing tons of our marketing budget due to this facts. So it would be great if anybody come forward and tell me any clue to test and help me to investigate.
204s mostly happen because of RAM issue, so boosting to a bigger instance type usually clears these up

I've gotten a 204 before and it was because there was a memory leak in app engine's ssl library. I was passing it the string to a cert file and it wasn't closing those files. The work-around to fix it was to handle the opening and closing of the file myself and pass it the file handle instead.

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.

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 have been making requests to my cloud REST Service over the two past weeks. Everything was fine until yesterday.
Over the past days, I kept re-publishing my service to the cloud to test some of its operations with a client. I DID NOT change anything in my web.config, just some method bodies.
Yesterday, by making the simplest GET request to my service, through my browser or Advanced Rest Client, i started getting the following error:
The server encountered an error processing the request. Please see the service help page for constructing valid requests to the service. The exception message is 'The underlying provider failed on Open.'. and so on
I suspect after doing my research that this means I clearly have a connection error with my database which I don't get since it was working fine so far.
I also tried to Stop and Start my service in the Azure Production Enviroment but without any luck. Also the server firewall is configured as it should be.
Any answers would be much appreciated.
Thanks.
In my experience these generally tend to be azure service outages. There is currently 'Scheduled maintenance' occurring on all DB instances which may be affecting you.
