Since you deleted the subtitles, did you update them after?
The request error seems to be from one of the online translators. Most of them are broken, so it's best to just disable them in Preferences -> Translators.
Though, you need a translator if you want to translate and embed name/choice/item descriptions etc. into the game. I've got ATLAS installed and it does the job fine, but there's an updated Google python file here and it also seems to work:

(Should replace the file with the same name in VNR -> Library -> Frameworks -> Sakura -> py -> libs -> google)
