Error code 34601 on battlefield one

I, as an older BF 1942 player, remember differently.
For Battlefield 1942 (released 2002), the problem was the shutdown of Gamespy (2014?) and support for the anti-cheat software PunkBuster in BF1942 has been discontinued.

GameSpy (https://en.wikipedia.org/wiki/GameSpy)

GameSpy Industries (the entity responsible for GameSpy multiplayer services) was bought from IGN Entertainment by Glu Mobile in August 2012, and proceeded in December to raise integration costs and shut down servers for many older games, including Star Wars: Battlefront, Sniper Elite, Microsoft Flight Simulator X, Saints Row 2, and Neverwinter Nights, with no warning to developers or players, much to the outrage of communities of those games. In April 2014, Glu announced that it would shut down the GameSpy servers on May 31, 2014, so its developers could focus on work for Glu's own services. Games that still used GameSpy are no longer able to offer online functionality or multiplayer services through GameSpy. While some publishers announced plans to migrate GameSpy-equipped games to other platforms (such as Steam or in-house servers), some publishers, such as Nintendo (who used the GameSpy servers as the basis of its Nintendo Wi-Fi Connection platform for DS and Wii games) did not, particularly due to the age of the affected games. Electronic Arts, in particular, announced 24 PC games, including titles such as Battlefield 2, the Crysis series, Saints Row 2 and the Star Wars: Battlefront series, would be affected by the end of GameSpy service.

Has anyone played Battlefield 1918 mod (https://www.imfdb.org/wiki/Battlefield:_1918) in the mid-2000s?
