I never had an issue for the past 40 days until today. I tried to clear my cache, sign out, restart the application, reinstall the extension. All the possible steps I have tried did not work.\n\nI also noticed my usage has exponentially shortened for this week, while last week I was able to use it continuously for 6 days, even exhausting my codex-spark usage during that period.\n\nIn only 39 hours, i’ve used 48% of my usage compared to last week, when I started to see usage drain exponentially once I used 30% of my usage. At 70% the drain became quite noticeable.\n\nWhen I was left with 3%, the usage seems to slow.\n\nThis week, usage is draining faster than ever. I noticed claude pro has slightly increased the usage, but you still face constraints in the 5 hour window compared to the doubling and usage of your weekly quota.\nCodex is still generous but the change in how it functions does not seem appropriate. I do like that ChatGPT pro request is not limited to the degree that it was last week.\n\nBack to my issue, why am I facing a connection error after trying to troubleshoot the problem from all possible angles?",
