Our HG Lab website and sourcecontrol went down and we are not sure why. This is the first time this has happened. We are getting the following error when we go to the website.

HgLab Error

There's something wrong under the hood.

System.ArgumentNullException: Value cannot be null.
Parameter name: context
   at Autofac.ResolutionExtensions.ResolveOptionalService(IComponentContext context, Service service, IEnumerable`1 parameters)
   at Autofac.ResolutionExtensions.ResolveOptional[TService](IComponentContext context, IEnumerable`1 parameters)

   at System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step)
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

we are getting the following error when we go to pull the data.
HTTP Error: 500 (Internal Server Error)
[command returned code 255 Tue Jul 07 12:48:25 2020]

Could you please help us out? We are not sure why this is happning.

    Hi Anton,

    I’m in the Mountain Timezone in the US. So 7AM in 1am here. I can do 7pm if that works. I can also get together at 1:30pm UTC if that works. That is 7:30am for me.

    I have a similar problem here. Restarting the HgLab machine seems to solve that problem, but it tends to show up again after some time (or incident). Can you elaborate on how you managed to solve it on your side?
