I have transports based at Alexandria. Sometimes they can sail through the Suez. Sometimes they can't. It's not a range issue. They are not grouped with anything else. I know they have the range because I sailed them from Aden (their previous base) through the Suez many times... when the game felt like allowing it (less than half the time).
Let me guess... You don't have Gibraltar, and it fails whenever you try to sail transport with troops in them past Suez. When you sail just plain warships and empty transports, it works, but full transports can't sail through Suez. Once you get Gibraltar, everything starts to work.
This must be a bug. Controlling Suez only gives a player partial access to the Suez canal, as follows:
1) Loaded transports can't sail through it.
2) Empty transports can sail through it.
3) Warships can sail through it.
Item 1 is cleared when the same side gets Gibraltar.
I checked the bug reporting guidelines, but can't be arsed to email a savegame to Paradox. Here's the reproduction notes, however:
0) Play Italy. Position troops so that you can capture Suez and Gibraltar. Base a full transport fleet in Tel Aviv.
Base an empty transport fleet in Tel Aviv.
Base a warship fleet in Tel Aviv.
1) Capture Suez. Look at the Canal info. Expected: "controlled by italy. you can sail through it."
2) Move the full transport fleet across the Canal. Expected: "out of range".
3) Move the empty transport fleet across the Canal. Expected: works.
4) Move the warship fleet across the Canal. Expected: works.
5) Capture Gibraltar. Look at the Suez canal info. Expected: same as 1).
6) Retry step 2. Expected: works.
