Maybe it depends on which particular Proton VPN server/country location is being used. Right now, with a server in Japan, Perplexity and Claude are accepting messages but not ChatGPT. But this is the first time I’ve had any of them work while Proton VPN was enabled.
Yeah w free Proton VPN...... I can only use one USA server
Newsflash! I left Proton VPN on inadvertently. It started to make websites such as X-Twitter non-loadable.
I have seen some great VPN deals for Christmas. Range of $25 for one year. $47 for 27 months. I will dig them up if you like
