Slaven Bilic described West Ham's performance as "unacceptable" in their 2-0 defeat at Watford.
The Hammers, who were third in the Premier League following last week's win over Chelsea, had beaten Arsenal, Liverpool and Manchester City on the road this season.
But their unbeaten away record was shattered by Watford, who scored goals either side of half-time through Odion Ighalo and dominated the contest throughout.
Bilic said: "It was a collective bad day. I told the players it was unacceptable and to make sure it was a one-off.
"You are going to lose games in this league but we weren't good today, apart from in the first 10 minutes.
"We gave them the win. Watford were full of respect for us - but when they smelt that we weren't penetrating enough, and that our movement and passes were slow and backwards, they smelt the opportunity to go at us.
"We learned a lesson, and I see no reason why we won't come back and play like we did before."
