I think I specified the checksum correctly, what could be the problem?

AFAICS, you've specified the wrong checksum:

$ wget https://github.com/Ckaf/pgn_parser/archive/v1.0.2.tar.gz
[...]
$  sha256sum v1.0.2.tar.gz 
d84c375f6acec42c8c3a64a05f6942e9c0289a8fd367a52f11099c866d9b1e22  v1.0.2.tar.gz

which differs from 78e455b3d4446e9cd8c191b78cb83a7edbc526894eb917ef0555346c1e5c7f86

There's progress: Now I see a bunch of lower-bounds failures:
chess_com_api.1.0.2 and pgn_parser.1.0.0 together fails with

Similarly lichess_api.1.0.2 and pgn_parser.1.0.0 together fails with

These kinds of cross-package incompatibilities are a source of red CI lights and time-consuming missing constraint hunting (both for you - and for opam-repo maintainers).
Since you are publishing 3 packages from the same repo - and from the same source tar-ball, I would recommend adding lock-step constraints, so that

• chess_com_api.1.0.2 works with lichess_api.1.0.2 and pgn_parser.1.0.2
• chess_com_api.1.0.3 works with lichess_api.1.0.3 and pgn_parser.1.0.3
• etc.

The lock-step constraints can be expressed with the version variable in an opam file as follows:

  "pgn_parser" {= version}

In a dune-project file you would need to prefix the version variable with a colon:

  (pgn_parser (= :version))
