Expo React Native fatal error java.net.SocketTimeoutException: timeout

While everything is working fine, I suddenly get this error. I delete the .expo folder, delete the node_modules folder and do npm install again. When I restart the computer later, it sometimes works fine, but sometimes I get this error. I received this error on my own phone, now I cannot run the React Native code neither on the phone nor on the emulator.enter image description here
