Hello Friends!
Suddenly i have faced with stupid problem and compleately stuck...
My personal "programmer's" tablet has stoped uploading GUI from Upload Service. Just displaying "Failed loading GUI".
I am not newbie with CF and i have checked everything i know - there are no Firewals or VPNs, all the devices has been rebooted many times, diffrent version of iViewer tested - nothing help..
I have tryed my personal mobile phone on the same setup - same net, same wifi, same PC with same GUI desiner and same design file - all worked as expected.
So it looks like it is a problem of my particular tablet, but can not understand what could go wrong with it - it is Samsung Galaxy Tab S5t (Android 11), i used it for many years, as testing device and as my personal home control tablet, all was fine, but all of a sudden it stoped working.
The only thing i did not try is a reset to a factory defaults, but i have a reasons to not doing this.
I will be very gratful for any advises what else should be checked.
With kind regards,
Eugene
