Cannot enter lobby due to VAL 43? Try these as workarounds:

Option 1 (Safest):

1. Use any other network aside from PLDT/Smart (for the Philippines) to load the game. You can connect through mobile hotspot, tether or other means, just NOT through PLDT/Smart.
2. Log into the game as usual.
3. Once you successfully enter, do a custom game by yourself, select a map and agent so that it brings you to your map. Once inside, connect through your main internet connection and hopefully you won't get disconnected in the process. If that was successful, you can play the game as usual.

Option 2 (Kind of risky but people are reporting success through this method)

1. Connect through a VPN service with Singapore/Hong Kong as location so that you stay in your current shard. THIS IS IMPORTANT AS SETTING YOUR VPN REGION OUTSIDE OF THE SHARD OF YOUR ACCOUNT IS IN MAY RESULT IN A BAN. Other countries in APAC shard include India and Australia.
2. Log into the game as usual.
3. Once you successfully enter, do a custom game by yourself, select a map and agent so that it brings you to your map. Once inside, disconnect from the VPN and hopefully you won't get disconnected in the process. If that was successful, you can play the game as usual.

These are sourced from various groups who had successfully done these steps. It seems like Cloudflare has an issue with regards to routing (photo not mine) that's why we're seeing these errors happening since at least over the weekend.

UPDATE: The VALORANT team is aware of the issue and is working with the affected ISP for the resolution.
