I2C Put One Termination Resistor: put one termination resistor at the Endend or on Each Slave Boardeach slave board

I have a system with an I2C bus wired just like this:

enter image description here

Which one is better: put the termination pull up-up resistor at the end of the connection (on the last board), or put the pull up-up resistors on each slave board?

I'm having a problem in that initially it can workworked, but after some time the I2C communication to the board failed and can't be recovered (SCL always stuck low when I observe using a logic analyzer). On each board there's a chip like PCA9685, MCP3424, PCA9674, etc.

My questions is whichWhich one is better: put the termination pull up resresistor at the end of the connection (on the last board), or put pull up resresistors on each slave board?

Because I'm having a problem, at initial in that initially it can work but after sometimessome time the I2C communication to board failed and can't be recovered (SCL always stuck low when I observe using logic analyzer) (on. On each board there's a chip like PCA9685, MCP3424, PCA9674, etc).
