Since the recent balance patch in Street Fighter V, many players have complained of issues surrounding their abilities to connect to CFN. While there are some proxy workarounds figured out by the community, the best solution should always come from the developers themselves.
Capcom has acknowledged these issues exist, and said that they will fix the issue within the month of April. There is, however, no mention of whether this fix will come in the form of a patch — or if they will also be addressing the multiple glitches found in the Season 3.5 update.
We’re aware some players are unable to log in after the update on 4/3. We’re planning to address this issue in April and will inform you when we have a specific date. We apologize for any inconvenience. https://t.co/tlzokzuuAO
