After the final whistle, the Liverpool defender delayed celebrating his team reaching the semi-finals of the tournament to entertain Hategan, who was in a flood of tears.
The Dutchman hugged the confused Hateganl crowd, who wanted to know why the former Celtic man had embraced the match officials.
Van Dijk explained the incident during a post-match press conference, where he revealed that Hategan had recently lost his mother.
"The man broke up, standing in tears because he had just lost his mother," van Dijk told the media.
"I wish he had strength and said that he had done it well.
"It's a small thing, but maybe that helps him."
Moments before tearfully embracing Hategan, van Dijk posted a Dutch place in the League Nation semi-final with a beautiful volley, which equalized to 2-2.
The next round of the tournament will be held in Portugal, where Ronald Koeman's men will face host, Switzerland or Portugal for a place in the final.
Koeman was pleased with the performance of his troops, saying: "The team shows character. We keep going.
"I don't think we played well. Maybe at this stage too much for us to play two matches in a short time against such high-quality opposition.
"Don't forget, this German is a very good team, maybe even better than France.
"But we also showed that we could recover while playing against this caliber."
German boss Joachim Low was very disappointed to see his team throw a two-goal lead but took a lot of positive results.
"I was a little disappointed with the results, but I have seen more positives than negatives in the whole game," he said.
"We had to make a third goal, which, of course, was bitter in the end. The faces in the dressing room were all down.
"Everyone wants to reward themselves today.
"It went a little through 2018, that we were unsuccessful.
"Basically we still have a lot of work to do. We only saw each other three weeks in total since the World Cup.
"The turmoil cannot happen from day to day, you cannot just plunge into a new team from the ground.
"Too little time for that to happen. However, the process has been running and has developed a little. "
