The Candystripes had, of course, played famous ties in the old European Cup against FK Lyn and Anderlecht in 1965/66 and Benfica in 1989/90.
However, the clash with NK Maribor was City's first and, to date, only appearance in the rebooted Champions League format.
City suffered a 0-2 defeat at the Brandywell, with Gregor Židan, a Slovenian international who also represented Croatia, and Damjan Gajser, another international, grabbing the goals.
They were beaten 1-0 in Slovenia, with Oskar Drobne on target.
