Scrape, unexpected error

[OklahomaGreyBeard]

I'm trying a program (sleep on lan) on my plex server that will let me hibernate or sleep the server from a remote computer via http. I setup a macro to scrape the url and it pauses VC for a couple of minutes then throws an error and continues with the macro.  Putting the same url in chrome or ie on the VC machine works fine.

The url is http://92.168.11.205:7770/hibernate which is the ip of the plex server and the port the sleep on lan program is running. using /sleep gives the same thing.

here's the info from the log after the error.

running in chrome the response from the loaded url is:

When you use Chrome, does it respond instantly or does it take a bit of time to get a successful response?

Does the machine go to sleep/hibernate?

It seems like the "server" is not returning a response to the http request, or is not returning it in a normal way.  Have you tried doing something similar with EventGhost, or is the plex server not running on Windows?

Using Chrome, the reply page in instantaneous, and the server immediately starts shutting down. It does not shut down from the scrape command, but I did switch to using eventghost and it works like a charm. I do wonder about the error though.

I installed the Windows version of this program and tested it here. I get the same error but there is no delay. The machine goes to sleep and the next action executes immediately. Basically, it works fine. I don't know if your Plex machine is running Windows.  I also only tested with suspend,  not hibernate.

I'll do some more investigation.

There are a lot of things about this that confuse me.  I've tried everything I can think of and I always get an error when trying to scrape this app.  I am receiving an error telling me that the server committed a protocol violation, but of course not which one.  What is also strange is that although I am not able to read the response back from the app it still goes to sleep immediately and the action completes immediately but shows an error.  I don't know what is different about your setup that it freezes VC and does not get the server to sleep.

In any case here is an alternative method that might work for you.  You only need tiny bit of python and it will probably not care about the protocol violation so it may work fine.

Paste this into your tree and edit the IP address and hopefully it will work.
