Bypassing the Ubi Launcher??

So I reinstalled SH5, had it going last night, added mods, feared I messed something up so uninstalled all of it then reinstalled. Went to login to Uplay for the first time again online and EVERY time it says "A ubisoft service is unavailable, try offline" But I can't because my first login has to be Online, is there a way to tell it Ive already logged in?? I just want to see if my dang mods are working correctly.
