Just tried to click in motherlode in the GFS0.5deg on some parameter selections; data were loaded without problems. Since our problems this morning, our operational data download from NOMADS also has been working again. But I don't know why it works now, as well as I don't know why it didn't in the morning, producing the error message I sent you. In any case we have not changed anything in our setting since some weeks. Thanks for the moment, if the problem should reappear I will send you another mail!
