Having issues with online sessions on PC

[nonokill1]

Hi! I need help ASAP! I am a player who frequently plays gta 5 online on pc. 3 days ago everything was going well... However, I was playing gta 5 online just as usual, and suddenly I had no more WiFi. I tried fixing the WiFi in various ways... However, I couldn’t seem to fix it! But that wasn’t to big of an issue because I could just call the WiFi company the next day and fix it. So I did. Everything went well, and we got it fixed. However, when I hopped back on gta 5 online on my pc to play with my buddies. I noticed something strange... Each time I tried joining them or they tried joining me. It would make me leave the session within 10 seconds and it would say on my screen that they left but on theirs it would say that I left. I was very confused... I started surfing on the web to find an answer to my problem. However, after hours and hours of searching. I couldn’t find anything that corresponded to my problem. But what I didn’t notice was that not only I couldn’t play with my friends but I couldn’t even join a normal session. Because the same thing would occur. At this point I don’t know what to do... If someone knows anything that could help I would gladly appreciate  it. Thank you.
