Failed to connect to oauth2.googleapis.com port 443: Connection timed out

[pdeberranger]

We are using the google api with php to authenticate our user. Since one week we have a lot of : Failed to connect to oauth2.googleapis.com port 443: Connection timed out. If we refresh it's works, but 1 of 2 time it's timed out.

What can i do ?

PHP Fatal error: Uncaught GuzzleHttp\Exception\ConnectException: cURL error 7: Failed to connect to oauth2.googleapis.com port 443: Connection timed out (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) in /var/www/fr/my.isartintra/vendor/guzzlehttp/guzzle/src/Handler/CurlFactory.php:200\nStack trace:

$this->GoogleClient = new \Google_Client(); $this->GoogleClient->setClientId($this->Client_id); $this->GoogleClient->setClientSecret($this->Client_secret); $this->GoogleClient->setRedirectUri($this->Redirect_uri); $this->GoogleClient->setScopes(['email', 'https://www.googleapis.com/auth/calendar.events.readonly']); $this->GoogleClient->setAccessType('offline'); $this->GooglePlus = new \Google_Service_Oauth2($this->GoogleClient);

We use GooglePlus to get the picture $user_name = $this->GooglePlus->userinfo->get()->name; $user_email = $this->GooglePlus->userinfo->get()->email; $user_google_picture = $this->GooglePlus->userinfo->get()->picture;

Many thanks for help.

Let me start with asking some questions.

What kind of environment you're running the code? Is it possible that the environment has a poor network connection, or the network bandwidth is pretty full at the moment?

Is this reproducible on other environment?

[pdeberranger]

We have two types of environments: Workstation (dev) Servers Tests were performed from several 4G, 600Mb, 2Gb network links

Since 26/11, the service seems to have been restored, we have not changed anything and we no longer have timeout.

@pdeberranger Thanks for the update!

I guess it was due to the backend issue. While such issues on the auth backend are problematic, I don't think there's anything we can do within our client library to improve things.

Let me close this, but feel free to open if you think differently.

Thanks again.

We're seeing similar issues from time to time as well. The problems usually persist for a couple of minutes but can also span hours to days with sporadic errors like:

• Failed to connect to oauth2.googleapis.com port 443: No route to host
• Failed to connect to oauth2.googleapis.com port 443: Connection timeout
• Connection timed out after X milliseconds
• Unknown SSL protocol error in connection

In rare cases, we've also seen misleading errors like "Invalid project ID ''. Project IDs must contain 6-63 lowercase letters, digits, or dashes. [...]" that hint to a client error but actually originated on the backend (see https://github.com/googleapis/google-cloud-php/issues/1673)

Though I realize there's not much the client lib can do (apart from retrying), it would be great to have an "official place" where such errors are tracked - especially for intrenal stakeholder communication.

I'm aware of https://status.cloud.google.com/ but that doesn't seem to pick up on more subtle outages.

Im currently resorting to Twitter, but that hardly feels like a good fit in terms of transparency, e.g.

I am having the same issue, it appears when many request are being sent... So the best solution is to retry until it dissapears?

[akash5100]

I am facing the same issue. Which is Error: HTTPSConnectionPool(host='oauth2.googleapis.com', port=443), until last day it was working just fine. All I have to do is keep retrying?

[pinkasey]

I got this issue today, for 3 hours. Go this:

cURL error 28: Failed to connect to oauth2.googleapis.com port 443 after 75200 ms: Connection timed out (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://oauth2.googleapis.com/token

@odedstr FYI

[badams2527]

We're still being affected by this intermittently. It prevents our APIs from creating pubsub messages for an irregular amount of time. Any workarounds for this besides adding retry logic?

[odedstr]

We had this issue recently and it was solved by the hosting provider. The problem was that some of the Google IP addresses were blocked by the hosting provider's Firewall, after our server tried to send too many simultaneous API calls to these IP addresses. They solved it by removing the blocks, and increasing the max number of allowed connections.

[badams2527]

Interesting, thanks. In this case that's super concerning considering we're getting this error from our containers in GKE :D I'll contact GCP support and see if there's anything they can do. Thanks for the response!

this is happened when i try to run my app when i change the host in firebase emulators for local testing, but i fixed the issue by rebuilding the app for ios, using npm run ios
