Problem with h2o. AutoML. Unexpected CURL error: getaddrinfo() thread failed to start

I'm trying to run a h2o.automl script, nothing too complex, that has worked before plenty of times on my current machine

autoML= h2o.automl(x = x,
               y = y, 
               training_frame = data.trainingtest.h2o, 
               leaderboard_frame = data.validation.h2o, 
               max_runtime_secs = 3600*3,
               exclude_algos = c("StackedEnsemble", "DeepLearning"))     

The problem is that I get the following error, and I don't know where to start looking for a solution

Error in .h2o.doSafeREST(h2oRestApiVersion = h2oRestApiVersion, urlSuffix = page, : Unexpected CURL error: getaddrinfo() thread failed to start

The problem arises when it is almost finished, so it is really annoying because the first times I ran it for three hours. Is there something that I can add to make the problem more approachable? has anyone faced something like this?
