first of all thanks for this wonderful project that works perfect. i have one issue that after 4-5 hours server on my ios doesn't respond. then when i restart my router it works perfectly again, is that any issue with my internet connection something i am missing from code side..!!

i have two device both work as client and server, i send the message from one device and receive to another device same from second device. in that case after some time, this communication not working, if i restart my router then the communication will start again...
