some ways and tips I have done as well as deleting / repairing cache through the settings button next to the close button in the warframe laucher, verification and optimization, I have done the results failed. and I have also uninstalled and reinstalled it still failed, lastly I used a VPN and it still failed ... but I can't try to cancel the cache via steam because the "verify integrity of game files" cannot be clicked ... and that only happens in Warframe ..
if I unistall Steam then I reinstall the biggest risk again, I will lose all the games and applications that I have installed on my PC ..
and I am from the ASIA Server.
for those who have a problem like this please help me vote so that it can be overcome by DE ...
