I don't know what happened but here is the summery! A few minutes ago (10-15), I wasn't able to visit the forum through my mobile phone, I was encountered with a timeout error. Currently I am using my laptop to make this post! And I was able to access the site (using VPN as always). After clearing the data I was able to access the site normally. Note that both the device were under the same WIFI network when the issue arose!
Any idea what could have caused it?

I haven’t witness any of this since have been using this forum and I log in my forum account on several mobile devices cause I do change my phone several times and still haven’t notice any error more over anytime I use the forum I don’t logged in with any vpn or so.
So I guess maybe the problem will be from your sever or maybe country sever or such cause I haven’t intercepted any of this error ever.
I don’t think the problem is from the forum or any maintenance activity but in my opinion I guess it could be your sever for your mobile phone or even the IP address of your mobile phone. If many have encountered such problems they could have voice out but only few could reply to this thread so I guess it only the few that encounter same problem.
And also @crypto library also said he encountered same problem and I could see both of you are from same country so I guess maybe it just your country sever that making this issues to pop up so maybe you will stick to making use of your pc for the main time.
