Anonymous login failing to connect with CM servers

[ericwoolard]

I have a pretty simple bot that uses SteamClient to login anonymously and make a call to get_product_info(), and recently noticed that my attempts at an anonymous login have started to fail once attempting to establish a connection to any of the bootstrapped CM servers. Have had no issues for over a year until now, and can't seem to figure out what's going on.

Logging just shows

15260 Bootstraping from builtin list
15260 Added 30 new CM addresses.
15260 Attempting Anonymous login
15260 Connect initiated.
15260 Attempting connection to ('208.78.164.12', 27017)
15260 Failed to connect. Retrying...

and continues to try additional CM servers, but fails on each.

Sound like you are on steam v0.9. Either update, or use set_credential_location() to maintain an up to date list of CMs.

Updating did the trick. Thanks!

As an extra note, I ran into several protobuf related errors after updating to 1.0.2, but lowering my protobuf version to 3.6.0 fixed those issues.

Well, it's working locally, however I'm still running into issues on a server running Ubuntu 14.04. Output just repeatedly spits out

28544 WebAPI boostrap failed: __init__() takes at most 1 positional argument (2 given)
28544 DNS boostrap failed: __init__() takes at most 1 positional argument (2 given)

until I kill the script.

I'm not passing anything to SteamClient() or directly modifying or instantiating CMClient nor CMServerList. The only calls I'm making with SteamClient are client.anonymous_login() and client.get_product_info(apps=[730], timeout=15).

I've made sure steam is v1.0.2 on both systems, and even put all dependencies on the same versions yet still have this issue on the Ubuntu server.

Any ideas what could be causing this?

[rossengeorgiev]

Very strange. What version of python are using?

Log message suggests it is failing here:

https://github.com/ValvePython/steam/blob/92c5107c7c300d55d37d9e681de8394d78fca841/steam/core/cm.py#L462 https://github.com/ValvePython/steam/blob/92c5107c7c300d55d37d9e681de8394d78fca841/steam/core/cm.py#L491

You can edit your local file and add:

self._LOG.exception(exp)

Re-run the script, and now there should be full stacktrace printed out when the error occures, which should have enough info to debug this further

I'm running Python 3.5 on the server. This is what I've got for bootstrap_from_webapi():

Seems it may be related to gevent? Like I said previously, in my troubleshooting I put all dependencies including gevent on the same version as my local test env, so I'm not really sure what would be the issue unless there's a component of gevent that I missed.

[rossengeorgiev]

Looks like bug in gevent, try different version. Also, update your ubuntu. 14 LTS is old, and since April is end of life.

[ericwoolard]

Upgrading ubuntu has been on the list for a while but unfortunately isn't feasible atm. Rolling back gevent to v1.4.0 and greenlet to v0.4.15 got everything working again. Thanks for your help!
